黎曼猜想文献

黎曼猜想文献黎曼猜想最早由德国数学家贝尔纳德·黎曼在1859年的一篇题为《关于函数的复变量》的论文中提出。

这篇论文发表在《哥廷根科学与文学学报》(Göttingische Gelehrte Anzeigen)上。

然而,黎曼在这篇论文中并没有直接论述黎曼猜想,而是提出了一些相关的概念和定理,为后来对黎曼猜想的研究奠定了基础。

黎曼猜想的原文(德文)可以在以下链接中找到:https://www.maths.tcd.ie/pub/HistMath/People/Riemann/Zeta/EZe ta.html除了黎曼的原始论文,还有许多对黎曼猜想的研究文献。

质数与合数的英语

质数与合数的英语Primes and CompositesThe world of numbers is a fascinating realm, filled with intricate patterns and captivating relationships. At the heart of this numerical landscape lie two distinct categories: primes and composites. These two groups, though seemingly simple, hold the key to unlocking the deeper mysteries of mathematics.Primes, the building blocks of the number system, are those positive integers greater than 1 that are only divisible by 1 and themselves. These special numbers, such as 2, 3, 5, 7, 11, and 13, possess a unique and unwavering property – they cannot be expressed as the product of two smaller positive integers. This fundamental characteristic sets them apart from their counterparts, the composites.Composites, on the other hand, are positive integers greater than 1 that can be expressed as the product of two or more smaller positive integers. These numbers, such as 4, 6, 8, 9, and 10, are not as "pure" as primes, as they can be broken down into smaller factors. Composites can be further divided into two subcategories: squarenumbers, which are the product of two equal integers, and non-square numbers, which are the product of two distinct integers.The relationship between primes and composites is a delicate and intricate dance, with each group playing a vital role in the grand scheme of mathematics. Primes, being the building blocks of the number system, serve as the foundation upon which all other numbers are constructed. They are the atoms of the numerical world, the indivisible entities that cannot be broken down any further. Composites, on the other hand, are the molecules – the complex structures formed by the combination of these prime "atoms."The study of primes and composites has captivated mathematicians for centuries, leading to the development of numerous fascinating theories and applications. One of the most intriguing aspects of this field is the distribution of primes throughout the number system. While primes may appear to be randomly scattered, mathematicians have discovered patterns and regularities in their occurrence, leading to the formulation of the Prime Number Theorem and the Riemann Hypothesis, two of the most significant unsolved problems in mathematics.The importance of primes and composites extends far beyond the realm of pure mathematics. These numerical categories have found applications in various fields, including cryptography, where theunique properties of primes are exploited to create secure communication systems. Primes are also crucial in the study of number theory, a branch of mathematics that delves into the intricate relationships between different types of numbers and their underlying structures.In the realm of computer science, the study of primes and composites has given rise to efficient algorithms for factoring large numbers, a crucial task in the field of cryptography. The ability to quickly identify the prime factors of a composite number has significant implications for the security of digital communication and the protection of sensitive information.Moreover, the exploration of primes and composites has led to the development of fascinating mathematical concepts, such as the Goldbach Conjecture, which states that every even integer greater than 2 can be expressed as the sum of two primes. This conjecture, which remains unproven despite its apparent simplicity, continues to captivate mathematicians and stimulate further research.In conclusion, the world of primes and composites is a rich and captivating domain, filled with intricate patterns, profound insights, and far-reaching applications. As we delve deeper into the study of these numerical categories, we uncover the hidden beauty and complexity that lie at the heart of the mathematical universe. Theexploration of primes and composites promises to yield new discoveries, challenging our understanding of the numerical landscape and pushing the boundaries of human knowledge.。

黎曼ζ函数Riemann zeta functionIn mathematics, the Riemann zeta function, named after German mathematician Bernhard Riemann, is a function of great significance in number theory because of its relation to the distribution of prime numbers. It also has applications in other areas such as physics, probability theory, and applied statistics. The Riemann hypothesis, a conjecture about the distribution of the zeros of the Riemann zeta function, is considered by many mathematicians to be the most important unsolved problem in pure mathematics.[1]DefinitionThe Riemann zeta-function ζ(s) is the function of a complex variable s initially defined by the following infinite series:As a Dirichlet series with bounded coefficient sequence this series converges absolutely to an analytic function on the open half-plane of s such that Re(s) > 1 and diverges on the open half-plane of s such that Re(s) < 1. The function defined by the series on the half-plane of convergence can however be continued analytically to all complex s≠ 1. For s= 1 the series is formally identical to the harmonic series which diverges to infinity. As a result, the zeta function becomes a meromorphic function of the complex variable s, which is holomorphic in the region {s∈ C : s≠1} of the complex plane and has a simple pole at s= 1 with residue 1.Specific valuesThe values of the zeta function obtained from integral arguments are called zeta constants. The following are the most commonly used values of the Riemann zeta function.this is the harmonic series.this is employed in calculating the critical temperature for a Bose–Einstein condensate in physics, and for spin-wave physics in magnetic systems.the demonstration of this equality is known as the Basel problem. The reciprocal of this sum answers the question: What is the probability that two numbers selected at random are relatively prime? [2]this is called Apéry's constant.Stefan–Boltzmann law and Wien approximation in physics.Euler product formulaThe connection between the zeta function and prime numberswas discovered by Leonhard Euler, who proved the identitywhere, by definition, the left hand side is ζ(s) and the infiniteproduct on the right hand side extends over all prime numbers p(such expressions are called Euler products):Both sides of the Euler product formula converge for Re(s) > 1. The proof of Euler's identity uses only the formula for the geometric series and the fundamental theorem of arithmetic. Since the harmonic series, obtained when s= 1, diverges, Euler's formula implies that there are infinitely many primes. For s an integer number, the Euler product formula can be used to calculate the probability that s randomly selected integers are relatively prime. It turns out that this probability is indeed 1/ζ(s). The functional equationThe Riemann zeta function satisfies the functional equationvalid for all complex numbers s, which relates its values at points s and 1 −s. Here, Γ denotes the gamma function. This functional equation was established by Riemann in his 1859 paper On the Number of Primes Less Than a Given Magnitude and used to construct the analytic continuation in the first place. An equivalent relationship was conjectured by Euler in 1749 for the functionAccording to André Weil, Riemann seems to have been very familiar with Euler's work on the subject.[3]The functional equation given by Riemann has to be interpreted analytically if any factors in the equation have a zero or pole. For instance, when s is 2, the right side has a simple zero in the sine factor and a simple pole in the Gamma factor, which cancel out and leave a nonzero finite value. Similarly, when s is 0, the right side has a simple zero in the sine factor and a simple pole in the zeta factor, which cancel out and leave a finite nonzero value. When s is 1, the right side has a simple pole in the Gamma factor that is not cancelled out by a zero in any other factor, which is consistent with the zeta-function on the left having a simple pole at 1.There is also a symmetric version of the functional equation, given by first definingThe functional equation is then given by(Riemann defined a similar but different function which he called ξ(t).)The functional equation also gives the asymptotic limit(GergőNemes, 2007)Zeros, the critical line, and the Riemann hypothesisThe functional equation shows that the Riemann zeta function has zeros at −2, −4, ... . These are called the trivial zeros. They are trivial in the sense that their existence is relatively easy to prove, for example, from sin(πs/2) being 0 in the functional equation. The non-trivial zeros have captured far more attention because their distribution not only is far less understood but, more importantly, their study yields impressive results concerning prime numbers and related objects in number theory. It is known that any non-trivial zero lies in the open strip {s∈ C: 0 < Re(s) < 1}, which is called the critical strip. The Riemann hypothesis, considered to be one of the greatest unsolved problems in mathematics, asserts that any non-trivial zero s has Re(s) = 1/2. In the theory of the Riemann zeta function, the set{s∈ C: Re(s) = 1/2} is called the critical line. For the Riemann zeta function on the critical line, see Z-function.The location of the Riemann zeta function's zeros is of great importance in the theory of numbers. From the fact that allnon-trivial zeros lie in the critical strip one can deduce the prime number theorem. A better result[4]is that ζ(σ+ i t) ≠ 0 whenever |t| ≥ 3 andThe strongest result of this kind one can hope for is the truth of the Riemann hypothesis, which would have many profound consequences in the theory of numbers.It is known that there are infinitely many zeros on the critical line. Littlewood showed that if the sequence (γn) contains the imaginary parts of all zeros in the upper half-plane in ascending order, thenThe critical line theorem asserts that a positive percentage of the nontrivial zeros lies on the critical line.In the critical strip, the zero with smallest non-negative imaginary part is 1/2 + i14.13472514... Directly from the functional equation one sees that the non-trivial zeros are symmetric about the axis Re(s) = 1/2. Furthermore, the fact that ζ(s) = ζ(s*)* for all complex s≠ 1 (* indicating complex conjugation) implies that the zeros of the Riemann zeta function are symmetric about the real axis.The statistics of the Riemann zeta zeros are a topic of interest to mathematicians because of their connection to big problems like the Riemann hypothesis, distribution of prime numbers, etc. Through connections with random matrix theory and quantum chaos, the appeal is even broader. The fractal structure of the Riemann zeta zero distribution has been studied using rescaled range analysis.[5] The self-similarity of the zero distribution is quite remarkable, and is characterized by a large fractal dimension of 1.9. This rather large fractal dimension is found over zeros covering at least fifteen orders of magnitude, and also for the zeros of other L-functions.The properties of the Riemann zeta function in the complex plane, specifically along parallels to the imaginary axis, has also been studied, by the relation to prime numbers, in recentphysical interference experiments, by decomposing the sum into two parts with opposite phases, ψ and ψ*, which then are brought to interference. [6]For sums involving the zeta-function at integer and half-integer values, see rational zeta series.[O] ReciprocalThe reciprocal of the zeta function may be expressed as a Dirichlet series over the Möbius functionμ(n):for every complex number s with real part > 1. There are a number of similar relations involving various well-known multiplicative functions; these are given in the article on the Dirichlet series.The Riemann hypothesis is equivalent to the claim that this expression is valid when the real part of s is greater than 1/2. [O] UniversalityThe critical strip of the Riemann zeta function has the remarkable property of universality. This zeta-function universality states that there exists some location on the critical strip that approximates any holomorphic function arbitrarily well. Since holomorphic functions are very general, this property is quite remarkable.[O] Representations[O] Mellin transformThe Mellin transform of a function f(x) is defined asin the region where the integral is defined. There are various expressions for the zeta-function as a Mellin transform. If the real part of s is greater than one, we havewhere Γ denotes the Gamma function. By subtracting off the first terms of the power series expansion of 1/(exp(x) −1) around zero, we can get the zeta-function in other regions. In particular, in the critical strip we haveand when the real part of s is between −1 and 0,We can also find expressions which relate to prime numbers and the prime number theorem. If π(x) is the prime-counting function, thenfor values with We can relate this to the Mellin transform of π(x) bywhereconverges forA similar Mellin transform involves the Riemann prime-counting function J(x), which counts prime powers p n with a weight of 1/n,so that Now we haveThese expressions can be used to prove the prime number theorem by means of the inverse Mellin transform. Riemann's prime-counting function is easier to work with, and π(x) can be recovered from it by Möbius inversion.Also, from the above (specifically, the second equation in this section), we can write the zeta function in the commonly seen form:[O] Laurent seriesThe Riemann zeta function is meromorphic with a single pole of order one at s= 1. It can therefore be expanded as a Laurent series about s= 1; the series development then isThe constants γn here are called the Stieltjes constants and can be defined by the limitThe constant term γ0 is the Euler-Mascheroni constant.[O] Rising factorialAnother series development valid for the entire complex plane iswhere is the rising factorial This can be used recursively to extend the Dirichlet series definition to all complex numbers.The Riemann zeta function also appears in a form similar to the Mellin transform in an integral over the Gauss-Kuzmin-Wirsing operator acting on x s−1; that context gives rise to a series expansion in terms of the falling factorial.[O] Hadamard productOn the basis of Weierstrass's factorization theorem, Hadamard gave the infinite product expansionwhere the product is over the non-trivial zeros ρ of ζ and the letter γ again denotes the Euler-Mascheroni constant. A simpler infinite product expansion isThis form clearly displays the simple pole at s = 1, the trivial zeros at −2, −4, ... due to the gamma function term in the denominator, and the non-trivial zeros at s = ρ.[O] Globally convergent seriesA globally convergent series for the zeta function, valid for all complex numbers s except s = 1, was conjectured by Konrad Knopp and proved by Helmut Hasse in 1930:The series only appeared in an Appendix to Hasse's paper, and did not become generally known until it was rediscovered more than 60 years later (see Sondow, 1994).Peter Borwein has shown a very rapidly convergent series suitable for high precision numerical calculations. The algorithm, making use of Chebyshev polynomials, is described in the article on the Dirichlet eta function.[O] ApplicationsAlthough mathematicians regard the Riemann zeta function as being primarily relevant to the "purest" of mathematical disciplines, number theory, it also occurs in applied statistics (see Zipf's law and Zipf-Mandelbrot law), physics, and the mathematical theory of musical tuning.During several physics-related calculations, one must evaluate the sum of the positive integers; paradoxically, on physical grounds one expects a finite answer. When this situation arises, there is typically a rigorous approach involving much in-depth analysis, as well as a "short-cut" solution relying on the Riemann zeta-function. The argument goes as follows: we wish to evaluate the sum 1 + 2 + 3 + 4 + · · ·, but we can rewrite it as a sum of reciprocals:The sum S appears to take the form of However, −1 lies outside of the domain for which the Dirichlet series for thezeta-function converges. However, a divergent series of positive terms such as this one can sometimes be represented in a reasonable way by the method of Ramanujan summation (see Hardy, Divergent Series.) Ramanujan summation involves an application of the Euler–Maclaurin summation formula, and when applied to the zeta-function, it extends its definition to the whole complex plane. In particularwhere the notation indicates Ramanujan summation.[7]For even powers we have:and for odd powers we have a relation with the Bernoulli numbers:Zeta function regularization is used as one possible means of regularization of divergent series in quantum field theory. In one notable example, the Riemann zeta-function shows up explicitly in the calculation of the Casimir effect.[O] GeneralizationsThere are a number of related zeta functions that can be considered to be generalizations of Riemann's zeta-function. These include the Hurwitz zeta functionwhich coincides with Riemann's zeta-function when q = 1 (note that the lower limit of summation in the Hurwitz zeta function is 0, not 1), the Dirichlet L-functions and the Dedekind zeta-function. For other related functions see the articles Zeta function andL-function.The polylogarithm is given bywhich coincides with Riemann's zeta-function when z = 1.The Lerch transcendent is given bywhich coincides with Riemann's zeta-function when z = 1 and q = 1 (note that the lower limit of summation in the Lerch transcendent is 0, not 1).The Clausen function that can be chosen as the real orimaginary part ofThe multiple zeta functions are defined byOne can analytically continue these functions to then-dimensional complex space. The special values of these functions are called multiple zeta values by number theorists and have been connected to many different branches in mathematics and physics.[O] Zeta-functions in fiction。

数学家高斯的故事

数学家高斯的故事

高斯(Gauss 1777~1855)生于Brunswick,位于现在德国中北部。

他的祖父是农民,父亲是泥水匠,母亲是一个石匠的女儿,有一个很聪明的弟弟,高斯这位舅舅,对小高斯很照顾,偶而会给他一些指导,而父亲可以说是一名「大老粗」,认为只有力气能挣钱,学问这种劳什子对穷人是没有用的。

高斯很早就展现过人才华,三岁时就能指出父亲帐册上的错误。

七岁时进了小学,在破旧的教室里上课,老师对学生并不好,常认为自己在穷乡僻壤教书是怀才不遇。

高斯十岁时,老师考了那道著名的「从一加到一百」,终于发现了高斯的才华,他知道自己的能力不足以教高斯,就从汉堡买了一本较深的数学书给高斯读。

同时,高斯和大他差不多十岁的助教Bartels变得很熟,而Bartels的能力也比老师高得多,后来成为大学教授,他教了高斯更多更深的数学。

老师和助教去拜访高斯的父亲,要他让高斯接受更高的教育,但高斯的父亲认为儿子应该像他一样,作个泥水匠,而且也没有钱让高斯继续读书,最后的结论是--去找有钱有势的人当高斯的赞助人,虽然他们不知道要到哪里找。

经过这次的访问,高斯免除了每天晚上织布的工作,每天和Bartels讨论数学,但不久之后,Bartels也没有什么东西可以教高斯了。

1788年高斯不顾父亲的反对进了高等学校。

数学老师看了高斯的作业后就要他不必再上数学课,而他的拉丁文不久也凌驾全班之上。

高斯1777年4月30日生于不伦瑞克的一个工匠家庭,1855年2月23日卒于哥廷根。

幼时家境贫困,但聪敏异常,受一贵族资助才进学校受教育。

1795~1798年在哥廷根大学学习,1798年转入黑尔姆施泰特大学,翌年因证明代数基本定理获博士学位。

从1807年起担任格丁根大学教授兼格丁根天文台台长直至逝世。

高斯的成就遍及数学的各个领域,在数论、非欧几何、微分几何、超几何级数、复变函数论以及椭圆函数论等方面均有开创性贡献。

他十分注重数学的应用,并且在对天文学、大地测量学和磁学的研究中也偏重于用数学方法进行研究。

高斯智断瓶中线
• • 高斯丌到20岁时,在许多学科上就已取得了丌小的成就。对亍高斯接二连三的 成功,邻居的几个小伙子很丌服气,决心要为难他一下。 小伙子们聚到一起冥怃苦想,终亍想出了一道难题。他们用一根细棉线系上一 块银币,然后再找来一个非常薄的玻璃瓶,把银币悬穸垂放在瓶中,瓶口用瓶 塞塞住,棉线的另一头也系在瓶塞上。准备好以后,他们小心翼翼地捧着瓶子,在大街上拦住高 斯,用挑衅的口吻说道,“你一天到晚捧著书本,拿着放大镜东游西逛,一副蛮有学问的样子, 你那么有本事,能丌碰破瓶子,丌去掉瓶塞,把瓶中的棉线弄断吗?” 高斯对他们这种无聊的挑衅很生气,本丌想理他们,可当他看了瓶子后,又觉得这道难题还的确 有些意怃,亍是认真地想着解题的办法来。繁华的大街商庖林立,人流如川。在小伙子为能难倒 高斯而得意乊时,大街上的围观者越来越多。大家兴趣甚浓,都在想着法子,但无济亍事,除了 摇头自嘲乊外,只好把期冀的目光投向高斯。高斯呢,眉头紧皱,一声丌吭。小伙子们更得意了, 他们为自己高明的难题而叫绝。有人甚至刁难道:“怂么样,你智力有限吧,实在解丌出,就把 你得到的那么多荣誉证书拿到大街上当众烧掉,以后别再逞能了。” 高斯的确气恼,但他仍兊制住,丌受围观者嘈杂吵嚷的影响而冷静怃考。他无意地看了看明媚的 阳光,又望了望那个瓶子,忽然高兴地叫道:“有办法了。”说着从口袋里拿出一面放大镜,对 着瓶子里的棉线照着,一分钟、两分钟..人们好奇地睁大了眼,随着钱币“铛”的一声掉落瓶底, 大家发现棉线被烧断了。 高斯高声说道:“我是把太阳光聚焦,让这个热度很高的焦点穹过瓶子,照射在棉线上,使棉线 烧断。太阳光帮了我的忙。” 人们丌由发出一阵欢呼声,那几个小伙子也佩服得连连赞叹。

此文发表在:Advances in Theoretical and Applied Mathematics (A TAM), ISSN 0793-4554, V ol. 7, №4, 2012, pp.417-424Proving Goldbach’s Conjecture by Two Number Axes’ Positive Half Lines which Reverse from Each Other’s DirectionsZhang TianshuNanhai west oil corporation,China offshore Petroleum,Zhanjiang city, Guangdong province, P.R.ChinaEmail: tianshu_zhang507@;AbstractWe know that every positive even number 2n(n≥3) can express in a sum which 3 plus an odd number 2k+1(k≥1) makes. And then, for any odd point 2k+1 (k≥1)at the number axis, if 2k+1 is an odd prime point, of course even number 3+(2k+1) is equal to the sum which odd prime number 2k+1 plus odd prime number 3makes; If 2k+1 is an odd composite point, then let 3<B<2k+1, where B is an odd prime point, and enable line segment B(2k+1) to equal line segment 3C. If C is an odd prime point, then even number 3+(2k+1) is equal to the sum which odd prime number B plus odd prime number C makes. So the proof for Goldbach’s Conjecture is converted to prove there be certainly such an odd prime point B at the number axis’s a line segment which take odd point 3 and odd point 2k+1 as ends, so as to prove the conjecture by such a method indirectly.KeywordsNumber theory, Goldbach’s Conjecture, Even number, Odd prime number, Mathematical induction, Two number axes’ positive half lines which reverse from each other’s direction, OD, PL, CL, and RPL.Basic ConceptsGoldbach’s conjecture states that every ev en number 2N is a sum of two prime numbers, and every odd number 2N+3 is a sum of three prime numbers, where N≥2.We shall prove the Goldbach’s conjecture thereinafter by odd points at two number axes’ positive half lines wh ich reverse from each other’s directions and which begin with odd point 3.First we must understand listed below basic concepts before the proof of the conjecture, in order to apply them in the proof.Axiom.Each and every even number 2n (n≥3) can express in a sum which 3 plus each odd number 2k+1 (k≥1) makes.Definition 1.A line segment which takes two odd points as two ends at the number axis’s positive half line which begins with odd point 3 is called an odd distance. “OD” is abbreviated from “odd distance”.The OD between odd point N and odd point N+2t is written as OD N(N+2t), where N≥3, and t≥1.A integer which the length of OD between two consecutive odd points expresses is 2.A length of OD between odd point 3 and each odd point is unique.Definition 2.An OD between odd point 3 and each odd prime point at the number axis’s positive half line which begins with odd point 3, otherwise called a prime length. “PL” is abbreviated from “prime length”, and “PLS”denotes the plural of PL.An integer which each length of from small to large PL expresses be successively 2, 4, 8, 10, 14, 16, 20, 26. . .Definition 3.An OD between odd point 3 and each odd composite point at the number axis’s positive half line which begins with odd point 3, otherwise called a composite length. “CL” is abbreviated from “composite length”.An integer which each length of from small to large CL expresses be successively 6, 12, 18, 22, 24, 30, 32. . .We know that positive integers and positive integers’ points at the number axis’s positive half line are one-to-one correspondence, namely each integer’s point at the number axis’s positive half line represen ts only a positive integer. The value of a positive integer expresses the length of the line segment between point 0 and the positive integer’s point here. When the line segment is longer, it can express in a sum of some shorter line segments; correspondingly the positive integer can also express in a sum of some smaller integers.Since each and every line segment between two consecutive integer’s points and the line segment between point 0 and point 1 have an identical length, hence when use the length as a unit to measure a line segment between two integer’s points or between point 0 and any integer’s point, the line segment has some such unit length, then the integer which the line segment expresses is exactly some.Since the proof for the conjecture relate merely to positive integers which are not less than 3, hence we take only the number axis’s positive half line which begins with odd point 3. However we stipulate that an integer which each integer’s point represents expresses yet the length of the line segment between the integer’s point and point 0. For example, an odd prime value which the right end’s point of any PL represents expresses yet the length of the line segment between the odd prime point and point 0 really.We can prove next three theorems easier according to above-mentioned some relations among line segments, integers’ points and integers.Theorem 1.If the OD which takes odd point F and odd prime point P S as two ends is equal to a PL, then even number3+F can express in a sum of two odd prime numbers, where F>P S.Proof.Odd prime point P S represents odd prime number P S, it expresses the length of the line segment from odd prime point P S to point 0.Though lack the line segment from odd point 3 to point 0 at the number axis’s positive half line which begins with odd point 3, but odd prime point P S represents yet odd prime P S according to above-mentioned stipulation;Let OD P S F=PL 3P b, odd prime point P b represents odd prime number P b, it expresses the length of the line segment from odd prime point P b to point 0. Since PL 3P b lack the segment from odd point 3 to point 0, therefore the integer which the length of PL 3P b expresses is even number P b-3, namely the integer which the length of OD P S F expresses is even number P b-3. Consequently there is F=P S+(P b-3), i.e. 3+F=odd prime P S + odd prime P b .Theorem 2.If even number 3+F can express in a sun of two odd prime numbers, then the OD which takes odd point 3 and odd point F as ends can express in a sun of two PLS, where F is an odd number which is more than 3.Proof.Suppose the two odd prime numbers are P b and P d, then there be 3+F= P b+P d.It is obvious that there be OD 3F=PL 3P b + OD P b F at the number axis’s positive half line which begins with odd point 3.Odd prime point P b represents odd prime number P b according to above-mentioned stipulation, then the length of line segment P b(3+F) is precisely P d, nevertheless P d expresses also the length of the line segment from odd prime point P d to point 0. Thereupon cut down 3 unit lengths of line segment P b(3+F), we obtain OD P b F; again cut down 3 unit lengths of the line segment from odd prime point P d to point 0, we obtain PL 3P d, then there be OD P b F=PL 3P d.Consequently there be OD 3F=PL 3P b + PL 3P d.Theorem 3.If the OD between odd point F and odd point 3can express in a sum of two PLS, then even number 3+F can express in a sum of two odd prime numbers, where F is an odd number which is more than 3. Proof.Suppose one of the two PLS is PL 3P S, then there be F>P S,and the OD between odd point F and odd prime point P S is another PL. Consequently even number 3+F can express in a sum of two odd prime numbers according to theorem 1.The ProofFirst let us give ordinal number K to from small to large each and every odd number 2k+1, where k≥1,then from small to large each and every even number which is not less than 6is equal to 3+(2k+1).We shall prove this conjecture by the mathematical induction thereinafter.1.When k=1, 2, 3 and 4, we getting even number be orderly 3+(2*1+1)=6=3+3, 3+(2*2+1)=8=3+5, 3+(2*3+1)=10=3+7 and 3+(2*4+1)=12=5+7. This shows that each of them can express in a sum of two odd prime numbers.2.Suppose k=m, the even number which3 plus №m odd number makes, i.e. 3+(2m+1) can express in a sum of two odd prime numbers, where m≥4.3.Prove that when k=m+1, the even number which 3 plus №(m+1) odd number makes, i.e. 3+(2m+3) can also express in a sum of two odd prime numbers.Proof.In case 2m+3 is an odd prime number, naturally even number 3+(2m+3)is the sum of odd prime number 3 plus odd prime number 2m+3 makes.When 2m+3 is an odd composite number, suppose that the greatest odd, then the OD between odd prime number which is less than 2m+3 is Pmand odd composite point 2m+3 is either a PL or a CL. prime point PmWhen the OD between odd prime point Pand odd composite point 2m+3 isma PL, the even number 3+(2m+3)can express in a sum of two odd prime numbers according to theorem 1.If the OD between odd prime point Pand odd composite point 2m+3 is amCL, then we need to prove that OD 3(2m+3)can express in a sum of two PLS, on purpose to use the theorem 3.When OD P m(2m+3) is a CL, from small to large odd composite number 2m+3 be successively 95, 119, 125, 145. . .First let us adopt two number axes’ positive half lines which reverse from each other’s directions and which begin with odd point 3.At first, enable end point 3 of either half line to coincide with odd point 2m+1 of another half line. Please, see first illustration:3 5 7 2m-3 2m+12m+1 2m-3 7 5 3First IllustrationSuch a coincident line segment can shorten or elongate, namely end point 3 of either half line can coincide with any odd point of another half line.This proof will perform at some such coincident line segments. And for certain of odd points at such a coincident line segment, we use usually names which mark at the rightward direction’s half line.We call PLS which belong both in the leftward direction’s half line and in a coincident line se gment “reverse PLS”. “RPLS” is abbreviated from “reverse PLS”, and “RPL” denotes the singular of RPLS.The RPLS whereby odd point 2k+1 at the rightward direction’s half line acts as the common right endmost point are written as RPLS2k+1,and RPL2k+1 denotes the singular, where k>1.This is known that each and every OD at a line segment which takes oddpoint 2m+1 and odd point 3 as two ends can express in a sum of a PL and a RPL according to preceding theorem 2 and the supposition of №2 step of the mathematical induction.We consider a PL and the RPL2k+1 wherewith to express together the length of OD 3(2k+1)as a pair of PLS, where k >1. One of the pair’s PLS is a PL which takes odd point 3 as the left endmost point, and another is a RPL2k+1 which takes odd point 2k+1 as the right endmost point. We consider the RPL2k+1 and another RPL2k+1 which equals the PL as twin RPLS2k+1.For a pair of PLS, the PL is either unequal or equal to the RPL2k+1. If the PL is unequal to the RPL2k+1, then longer one is more than a half of OD 3(2k+1), yet another is less than the half. If the PL is equal to the RPL2k+1, then either is equal to the half. A pair of PLS has a common end’s point.Since each of RPLS2k-1 is equal to a RPL2k+1,and their both left endmost points are consecutive odd points, and their both right endmost points are consecutive odd points too. So seriatim leftwards move RPLS2k+1to become RPLS2k-y, then part left endmost points of RPLS2k+1 plus RPLS2k-y coincide monogamously with part odd prime points at OD 3(2k+1), where y=1, 3, 5, ...Thus let us begin with odd point 2m+1, leftward take seriatim each odd point 2m-y+2 as a common right endmost point of RPLS2m-y+2, where y= 1, 3, 5, 7 ... ỹ ...Suppose that y increases orderly to odd number ỹ,and∑ part left endmostpoints of RPLS2m-y+2(1≤y≤ỹ+2) coincide just right with all odd prime points at OD 3(2m+1) monogamously, then there are altogether(ỹ+3)/2 odd points at OD (2m-ỹ)(2m+1), and let μ=(ỹ+3)/2.Let us separate seriatim OD 3(2m-y+2) (y=1, 3, 5,…) from each coincident line segment of two such half lines, and arrange them from top to bottom orderly. After that, put an odd prime number which each odd prime point at the rightward direction’s half line expresses to on the odd prime point, and put another odd prime number which each left endmost point of RPLS2m-y+2 at the leftward direction’s half line expresses to beneath the odd prime point.For example, when 2m+3=95, 2m+1=93, 2m-1=91 and 2m-ỹ =89,μ=3. For the distributer of odd prime points which coincide monogamously with left endmost points of RPLS95, RPLS93, RPLS91, RPLS89 and RPLS87, please see second illustration:OD 3(95)19 31 37 61 67 7979 67 61 37 31 19OD 3(93)7 13 17 23 29 37 43 53 59 67 73 79 83 8989 83 79 73 67 59 53 43 37 29 23 17 13 7 OD 3(91) 5 11 23 41 47 53 71 83 8989 83 71 53 47 41 23 11 5 OD 3(89)13 19 31 61 73 7979 73 61 31 19 13OD 3(87) 7 11 17 19 23 29 31 37 43 47 53 59 61 67 71 73 79 8383 79 73 71 67 61 59 53 47 43 37 31 29 23 19 17 11 7Second IllustrationTwo left endmost points of twin RPLS2m-y+2 at OD 3(2m-y+2) coincide monogamously with two odd prime points, they assume always bilateral symmetry whereby the centric point of OD 3(2m-y+2)acts as symmetriccentric. If the centric point is an odd prime point, then it is both the left endmost point of RPL2m-y+2 and the odd prime point which coincides with the left endmost point, e.g. centric point 47 of OD3(91) in above-cited that example.We consider each odd prime point which coincides with a left endmost point of RPLS2m-ỹ alone as a characteristic odd prime point, at OD 3(2m+1). Thus it can seen, there is at least one characteristic odd prime point at OD 3(2m-ỹ) according to aforesaid the way of making things, e.g. odd prime points 19, 31 and 61 at OD 3(89) in above-cited that example.Whereas there is not any such characteristic odd prime point in odd prime points which coincide monogamously with left endmost points of RPLS2m+1 plus RPLS2m-1 ... plus RPLS2m-ỹ+2.In other words, every characteristic odd prime point is not any left endmost point of RPLS2m+1plus RPLS2m-1 ... plus RPLS2k-ỹ+2.Moreover left endmost points of RPLS2m-y are №1 odd points on the lefts of left endmost points of RPLS2m-y+2monogamously, where y is an odd number≥1.Consequently, №1 odd point on the left of each and every characteristic odd prime point isn’t a ny left endmost point of RPLS2m-1plus RPLS2m-3…plus RPLS2m-ỹ. — {1}Since each RPL2m-y+2 is equal to a PL at OD 3(2m-y+2).In addition, odd prime points which coincide monogamously with left endmost points of RPLS2m+1 plus RPLS2m-1 ... plus RPLS2m-ỹare all odd prime points at OD 3(2m+1).Hence considering length, at OD 3(2m+1) RPLS whose left endmost points coincide monogamously with all odd prime points are all RPLS at OD 3(2m+1), irrespective of the frequency of RPLS on identical length. Evidently the longest RPL at OD 3(2m+1)is equal to PL 3Pm.When OD P m(2m+3) is a CL, let us review aforesaid the way of making thing once again, namely begin with odd point 2m+1, leftward take seriatim each odd point 2m-y+2 as a common right endmost point of RPLS2m-y+2, and∑ part left endmost points of RPLS2m-y+2(1≤y≤ỹ+2) coincide just right with all odd prime points at OD 3(2m+1) monogamously.Which one of left endmost points of RPLS2m-y+2(1≤y≤ỹ+2) coincides first with odd prime point 3? Naturally it can only be the left endmost point ofthe longest RPL Pm whereby odd prime point Pmacts as the right endmostpoint.Besides all coincidences for odd prime points at OD 3(2m+1) begin with left endmost points of RPLS2m+1, whereas left endmost points of RPLS2m-ỹare final one series in the event that all odd prime points at OD 3(2m+1) are coincided just right by left endmost points of RPLS.Therefore odd point 2m-ỹ as the common right endmost point of RPLS2m-ỹcannot lie on the right of odd prime point Pm, then odd point 2m-ỹ-2 canonly lie on the left of odd prime point Pm. This shows that every RPL2m-ỹ-2 atOD 3(2m-ỹ-2) is shorter than PL 3 Pm.In addition, №1odd point on the left of a left endmost point of each and every RPL2k-ỹ is a left endmost point of RPLS2k-ỹ-2.Therefore each and every RPL2m-ỹ-2can extend contrary into at least one RPL2m-y+2, where y is a positive odd number ≤ỹ+2.That is to say, every left endmost point of RPLS2m-ỹ-2 is surely at least one left endmost point of RPLS2k-y+2.Since left endmost points of RPLS2m-ỹ-2 lie monogamously at №1 odd point on the left of left endmost points of RPLS2m-ỹ including characteristic odd prime points.Consequently, №1 odd point on the left of each and every characteristic odd prime point is surely a left endmost point of RPLS2m-y+2, where 1≤y≤ỹ+2.—— {2}So we draw inevitably such a conclusion that №1 odd point on the left of each and every characteristic odd prime point can only be a left endmost point of RPLS2m+1 under these qualifications which satisfy both above-reached conclusion {1}and above-reached conclusion {2}.Such being the case, let us rightwards move a RPL2m+1 whose left endmost point lies at №1odd point on the left of any characteristic odd prime point to adjacent odd points, then the RPL2m+1 is moved into a RPL2m+3. Evidently the left endmost point of the RPL2m+3is the characteristic odd prime point, and its right endmost point is odd point 2m+3.So OD 3(2m+3) can express in a sum of two PLS, and the commonendmost point of the two PLS is exactly the characteristic odd prime point.(2m+3) is a CL, likewise OD Thus far we have proven that even if OD Pm3(2m+3) can also express in a sum of two PLS.Consequently even number which 3 plus №(m+1)odd number makes, i.e. 3+(2m+3) can also express in a sum of two odd prime numbers according to aforementioned theorem 3.Proceed from a proven conclusion to prove a larger even number for each once, then via infinite many an once, namely let k to equal each and every natural number, we reach exactly a conclusion that every even number 3+(2k+1) can express in a sum of two odd prime numbers, where k≥1.To wit every even number 2N can express in a sum of two odd prime numbers, where N>2.In addition let N =2, get 2N=4=even prime number 2+even prime number 2. Consequently every even number 2N can express in a sum of two prime numbers, where N≥2.Since every odd number 2N+3 can express in a sum which a prime number plus the even number makes, consequently every odd number 2N+3 can express in a sum of three prime numbers, where N≥2.To sum up, we have proven that two propositions of the Goldbach’s conjecture are tenable, thus Goldbach’s conjecture holds water.附,翻译成汉语:利用互为反向数轴的正射线证明哥德巴赫猜想张天树Tianshu_zhang507@摘要我们知道,依次增大的每一个正偶数2n(n≧3)可以表示成3分别与依次增大的一个奇数2k+1(k≧1)之和.于是,对于数轴上的任意一个奇数点2k+1(k≧1),如果2k+1是一个奇素数点,当然,偶数3+(2k+1)可等于奇素数2k+1 与奇素数 3 之和;如果2k+1是一个奇合数点,那么,取3<B<2k+1,这里,B是一个奇素数点,且使线段B(2k+1)等于线段3C. 如果C是一个奇素数点,那么, 偶数3+(2k+1)等于奇素数B与奇素数C之和.于是对哥德巴赫猜想的证明就变换成了去证明:在数轴的以奇数点3和2k+1为端点的线段上,总是存在着这样的奇素数点B,以此方法来间接地证明哥德巴赫猜想.关键词数论、哥德巴赫猜想、数学归纳法、偶数、奇素数、互为反方向的数轴的正射线、奇距、素长、合长和反向素长.基本慨念哥德巴赫猜想表为:每一个偶数2N都是两个素数之和,每一个奇数2N+3都是三个素数之和,这里N≧2.本文将用互为反方向的两条数轴的从奇数点3开始的正方向射线上的奇数点来证明这个猜想.在证明这个猜想之前,我们先要熟知下述的基本慨念,以便在证明的过程中应用它们.公理.依次增大的每一个正偶数2n(n≧3)可以表示成3分别与依次增大的一个奇数2k+1(k≧1)之和.定义1. 在数轴的从奇数点3开始的正方向射线上,以任意两个奇数点为端点的线段,称为这两个奇数点之间的距离,简称奇距.我们用符号“OD”表示奇距.奇数点N与奇数点N+2t之间的奇距,写成OD N(N+2t),这里N≧3,t≧1. 相邻两个奇数点之间的奇距是2,奇数点3与各个奇数点之间的奇距长度,都是唯一的.定义2.在数轴的从奇数点3开始的正方向射线上,以任意一个奇素数点和奇数点3为端点的奇距,也被称为这个奇素数点的素长,并用符号“PL”表示一条素长,和符号“PLS”表示至少两条素长,即素长的复数.从小到大的素长依次是: 2、4、8、10、14、16、20、26. . . . . .定义3.在数轴的从奇数点3开始的正方向射线上,以任意一个奇合数点和奇数点3为端点的奇距,又被称为这个奇合数点的合长,并用符号“C L”表示一条合长.从小到大的合长依次是: 6、12、18、22、24、30、32. . . . . .我们知道,在数轴的正方向射线上的整数点与正整数是一一对应的.也就是说,在数轴的正方向射线上,每一个整数点只代表一个整数,这个整数的值在这里表示这个整数点距0点的线段长度. 当这条线段较长时,它可表为若干条线段之和. 因此,这个整数也可表为若干个整数之和. 且因为0点与1点、以及相邻两个整数点之间的线段长度都是相等的,当我们把这些相等线段每条的长度作为1个长度单位去度量任意一个整数点距0点的线段或任意两个整数点之间的线段长度时,该线段有多少个这样的长度单位,它就代表多大的整数.因为本文的证明仅仅用到不小于3的整数,所以,我们只取数轴的从奇数点3开始的正方向射线,但我们规定:在这射线上的每个整数点代表的整数值仍然是指这个整数点距0点的线段长度. 例如,在这射线上任意一条素长的右端点所代表的奇素数值,实际上是指这个奇素数点距0点的线段长度.根据以上所述,我们很容易地证明以下三条定理:定理1.如果以奇数点F和奇素数点P S 为端点的奇距等于一条素长,那么,偶数3+F可表为两个奇素数之和,这里F>P S.证明:奇素数点P S代表奇素数P S,P S的值表示奇素数点P S到0点的长度.在数轴的从奇数点3开始的正方向射线上虽然缺少从奇数点3到0点的一段,但是按照前面的规定,奇素数点P S仍然代表奇素数P S;令OD P S F=PL 3P b,奇素数点P b代表奇素数P b,P b的值表示奇素数点P b 到0点的长度. 但是,PL 3P b缺少从奇数点3到0点的一段,因此,PL 3P b 的长度表示的整数是偶数P b-3,即OD P S F的长度表示的整数是偶数P b-3. 所以, F=P S+(P b-3),即3+F=奇素数P S+奇素数P b.定理2. 如果偶数3+F可表为两个奇素数之和,那么,以奇数点F和奇数点3为端点的奇距可表为两条素长之和,这里F是一个大于3的奇数.证明:假设这两个奇素数为P b和P d,则有3+F= P b+P d. 显然,在数轴的从奇数点3开始的正方向射线上,OD 3F=PL 3P b + OD P b F. 根据前面的规定,奇素数点P b代表奇素数P b,那么,线段P b(3+F)的长度就是P d,该长度是指从奇素数点P d到0点的线段长度.在线段P b(3+F)上去掉3个单位长度,得到OD P b F;在从奇素数点P d到0点的线段上去掉3个单位长度,得到PL 3P d,于是,OD P b F=PL 3P d.所以, OD 3F=PL 3P b + PL 3P d.定理3.如果奇数点F与奇数点3之间的奇距可表为两条素长之和,那么,偶数3+F可表为两个奇素数之和,这里F是一个大于3的奇数.证明:假设这两条素长中的一条是PL 3P S,那么,F>P S,且奇数点F与奇素数点P S 之间的奇距是另一条素长. 根据定理1,偶数3+F可表为两个奇素数之和.证明首先,让我们以自然数k给每一个依次增大的奇数2k+1编上序号,这里k≧1,那么,每一个不小于6的依次增大的偶数等于3+(2k+1). 在下文中, 我们将运用数学归纳法来证明这个猜想.1.当k= 1、2、3和4时,我们依次得到的偶数: 3+(2×1+1)=6=3+3,3+(2×2+1)=8=3+5,3+(2×3+1)=10=3+7或5+5,3+(2×4+1)=12=5+7都可表为两个奇素数之和.2.假设当k=m时,3加上第m个奇数所得的偶数、即3+(2m+1)可表为两个奇素数之和,这里m≧4.3.证明:当k=m+1时,3加上第m+1个奇数所得的偶数、即3+(2m+3)也可表为两个奇素数之和.证明如果2m+3是一个奇素数,当然,偶数3+(2m+3)可表为奇素数3与奇素数2m+3之和.当2m+3是一个奇合数时,假设小于2m+3的最大奇素数为P m,那么,奇合数点2m+3与奇素数点P m之间的奇距或是一条素长,或是一条合长.当奇合数点2m+3与奇素数点P m之间的奇距是一条素长时,根据定理1,偶数3+(2m+3)可表为两个奇素数之和.如果奇合数点2m+3与奇素数点P m之间的奇距是一条合长,我们则需要证明OD 3(2m+3)可表为两条素长之和,以便应用定理3.当OD P m(2m+3)是一条合长时,2m+3从小到大的值依次是95、119、125、145. . . . . .首先,让我们采用两条互为相反方向的数轴的从奇数点3开始的正方向射线,最初,让一条射线上的奇数点3与另一条射线上的奇数点2m+1重合. 请参看第一图:3 5 7 2m-3 2m+12m+1 2m-3 7 5 3第一图这两条射线互相重合的线段能够缩短或伸长,也就是说,一条射线的端点3能够重合另一条射线的任意一个奇数点.本文的整个证明将在这样互相重合、且可伸缩的线段上施行,并且,对这线段上互相重合后的一个奇数点,我们主要使用它在向右方向射线上的名称.我们把既属于向左方向射线,又在两条射线互相重合的线段上的素长称为“反向素长”. 一条反向素长用符号“RPL”表示,它的复数表为“RPLS”. 以向右方向射线上的奇数点2k+1作为共同右端点的至少两条反向素长被写作RPLS2k+1,以及RPL2k+1表示其中的一条,这里k>1.根据前列的定理2和数学归纳法中第二步的假设,我们知道,在以奇数点2m+1和奇数点3为端点的线段上的各条奇距,都能够表为一条素长与一条反向素长之和. 我们把表示OD 3(2k+1)为两条素长之和的两条素长看作是一对素长,这里k>1. 在这对素长中,一条是以奇数点3为左端点的素长,另一条则是以奇数点2k+1为右端点的反向素长. 我们把这对素长中的反向素长和在长度上等于这对素长中素长的另一条以奇数点2k+1为右端点的反向素长看作是孪生的反向素长.对于共表OD 3(2k+1)长度的一对素长,如果它们不等,那么,较长的一条比OD 3(2k+1)的一半长,而另一条则比这一半短. 如果这两条素长相等,那么,每一条都等于OD 3(2k+1)的一半.共表OD 3(2k+1)长度的一对素长,它们有一个共同的端点.因为在长度上每一条RPL2k-1 等于一条RPL2k+1. 并且,它们的左端点是相邻的奇数点,右端点也是相邻的奇数点. 于是,逐点向左移动RPLS2k+1使之成为RPLS2k-y,那么,RPLS2k+1和RPLS2k-y 的部分左端点就一对一地重合OD 3(2k+1)上的奇素数点,这儿y=1, 3, 5, …...因此,让我们在数轴的从奇数点3开始的正方向射线上,从奇数点2m+1开始,向左依次取每一个奇数点2m-y+2作为反向素长的共同右端点,这里y=1、3、5、7、...ỹ、...假设y依次增大到奇数ỹ,且RPLS2m+1、RPLS2m-1 ... RPLS2m-ỹ+2和RPLS2m-ỹ的部份左端点一对一地恰好重合完OD 3(2m+1)上的全部奇素数点,那么,在OD(2m- ỹ)(2m+1)上共有(ỹ+3)/2个奇数点,并且令μ =(ỹ+3)/2.然后,我们按照从长到短的次序,从两条射线的重合段中依次分离出OD 3(2m-y+2),并把它们从上到下依次排列起来,还把向右方向射线上表示奇素数点的奇素数放在这个奇素数点的上方,把重合这奇素数点的表示反向素长左端点的奇素数放在它的下方.例如:当2m+3=95时,2m+1=93, 2m-1=91和2m-ỹ=89,μ=3. 对于OD 3(95)、OD 3(93)、OD 3(91) 、OD 3(89) 和OD 3(87)上反向素长左端点重合奇素数点的分布情况,如下图:OD 5(95)19 31 37 61 67 7979 67 61 37 31 19OD 5(93) 7 13 17 23 29 37 43 53 59 67 73 79 83 8989 83 79 73 67 59 53 43 37 29 23 17 13 7OD 5(91)5 11 23 41 47 53 71 83 8989 83 71 53 47 41 23 11 5OD 5(89) 13 19 31 61 73 7979 73 61 31 19 13OD 5(87) 7 11 17 19 23 29 31 37 43 47 53 59 61 67 71 73 79 8383 79 73 71 67 61 59 53 47 43 37 31 29 23 19 17 11 7第二图在OD 3(2m-y+2)上,孪生反向素长的两个左端点一对一重合的两个奇素数点,以该奇距的中点为对称中心左右对称. 如果该奇距的中点是一个奇素数点,那么,它既是反向素长的左端点,又是这个左端点重合的奇素数点,例如,在上面引用例子中,OD 3(91)的中点47.在OD 3(2m+1)上,我们仅仅把唯一由RPLS2m-ỹ的左端点重合的奇素数点,即在RPLS2m+1、RPLS2m-1、...和RPLS2m-ỹ+2的左端点一一重合的奇素数点中没有的奇素数点看作是特有的奇素数点. 那么,根据上述的作法,在RPLS2m-ỹ的左端点一一重合的奇素数点中,有至少一个特有的奇素数点.例如,上面所举那个例子中,在OD 3(89)上的奇素数点19、31和61.因为在RPLS2m+1、RPLS2m-1、...和RPLS2m-ỹ+2的左端点一一重合的奇素数点中,没有一个特有的奇素数点. 换言之,每一个特有的奇素数点都不是RPLS2m+1、RPLS2m-1、...和RPLS2m-ỹ+2的左端点.又RPLS2m-y+2的左端点左边的第一个奇数点是RPLS2m-y的左端点,这里y是≧1的正奇数.所以,在每一个特有奇素数点左边的第一个奇数点不是RPLS2m-1、RPLS2m-3、...和RPLS2m-ỹ的左端点.--- {1}因为在OD 3(2m-y+2)上,每一条反向素长等于一条素长. 加之,RPLS2m+1、RPLS2m-1、...和RPLS2m-ỹ的左端点一一重合的奇素数点是OD 3(2m+1)上全部的奇素数点.因此,仅以长度而言,在OD 3(2m+1)上,其左端点一对一地重合完全部奇素数点的反向素长是OD 3(2m+1)上全部的反向素长,而不与具有同一长度的反向素长的条数有关.显然,在OD 3(2m+1)上的全部反向素长中,最长的反向素长等于PL 3P m.当奇合数点2m+3与奇素数点P m之间的奇距是一条合长时,让我们回顾前述的作法,即从2m+1开始,向左依次取每一个奇数点作为反向素长的共同右端点,并且,RPLS2m+1、RPLS2m-1、...和RPLS2m-ỹ的左端点一对一重合的奇素数点是OD 3(2m+1)上全部的奇素数点.究竟哪一条反向素长的左端点首先重合奇素数点3呢?显然,它仅仅能够是以奇素数点P m为右端点的最长的反向素长的左端点.又从RPLS2m+1的左端点开始,RPLS2m-ỹ的左端点是重合完OD 3(2m+1)上全部奇素数点的最后一组.所以,作为RPLS2m-ỹ的共同右端点的奇数点2m-ỹ不能位于奇素数点P m的右边,于是,奇数点2m-ỹ-2位于奇素数点P m的左边. 由此可知,在OD 3(2m- ỹ-2)上的每一条反向素长都比PL 3P m短.又因为在RPLS2m-ỹ的左端点左边的第一个奇数点全部是RPLS2m-ỹ-2的左端点.所以,每一条RPL2m-ỹ-2都能反向延长成为至少一条RPL2m-y+2. 那就是说,RPLS2m-ỹ-2的每个左端点都一定是RPLS2m-y+2的至少一条的左端点,这里y是≦ỹ+2的正奇数.因为RPLS2m-ỹ-2的左端点一对一地全部在RPLS2m-ỹ左端点(包括特有奇素数点)左边的第一个奇数点上,于是,在特有奇素数点左边的第一个奇数点一定是RPLS2m-y+2的左端点,这里y是≦ỹ+2的正奇数. ---{2}所以,在既要满足结论{1}、又要满足结论{2}的情况下,我们只能够得出: 在特有奇素数点左边的第一个奇数点是RPLS2m+1的左端点.既然如此,让我们向右移动任意一条这样的PLS2m+1到相邻的奇数点,那么,这条PLS2m+1被移动成了一条PLS2m+3. 显然,这条PLS2m+3的左端点重合这个特有奇素数点,而它的右端点是奇数点2m+3.这样,OD 3(2m+3)可以被表为两条素长之和,这两条素长的共同端点就是这个特有奇素数点.到此为止,我们已经证明了: 当OD P m(2m+3)是一条合长时,OD 3(2m+3)也能表为两条素长之和.那么,根据定理3,3加上第m+1个奇数所得的偶数,即3+(2m+3)可以表示成两个奇素数之和.每次都从已证得的结论出发,就可以推出:当k等于每一个自然数时,每一个偶数3+(2k+1)都可以表示成两个奇素数之和. 即当N>2时,每一个偶数2N都可以表示成两个奇素数之和.又当N=2时,有2N=4=偶素数2+偶素数2.所以,每一个偶数2N都可以表示成两个素数之和,这里N≧2.因为每一个奇数2N+3等于偶数2N加上奇素数3,因此,每一个奇数2N+3都可以表示成三个素数之和,这里N≧2.综上所述,我们已经证明了哥德巴赫猜想的两个命题都是站得住脚的,因此,哥德巴赫猜想成立.。

我心中最崇拜的数学家高斯作文

我心中最崇拜的数学家高斯作文

我心中最崇拜的数学家高斯作文Gauss, a prominent mathematician and physicist, is undeniably oneof the most revered figures in the history of mathematics. He made significant contributions to various fields such as number theory, algebra, and geometry, leaving a lasting impact on the development of mathematics. His groundbreaking work continues to inspire generations of mathematicians around the world.高斯,一位著名的数学家和物理学家,无疑是数学史上最受尊敬的人物之一。

他在各个领域如数论、代数和几何学上做出了重大贡献,对数学的发展产生了深远影响。

他的突破性工作继续激励着世界各地的数学家们。

One of Gauss's most famous contributions is his work in number theory, particularly in the field of modular arithmetic. He developed the concept of congruence, which revolutionized the study of prime numbers and paved the way for modern cryptography. His insights into the distribution of prime numbers laid the foundation for the Riemann hypothesis, a fundamental conjecture in mathematics that remains unsolved to this day.高斯最著名的贡献之一是他在数论领域的工作,特别是在模算术领域。

素数分布的渐近定理

素数分布的渐近定理

素数分布的渐近定理是指素数在自然数范围内的分布规律。

其中最著名的渐近定理是由数论领域的数学家、数论分析的奠基人之一、德国数学家高斯(Carl Friedrich Gauss)提出的。

高斯的渐近定理,也称为高斯素数定理(Gauss's Prime Number Theorem),表明在自然数范围内,大致每当自然数n增长一倍时,小于等于n的素数的数量大致也增长一倍。

具体地说,令π(n)表示小于等于n的素数的个数,那么根据高斯的渐近定理,当n趋近于无穷大时,有以下近似关系:
π(n) ~ n / ln(n)
这里ln(n)表示n的自然对数。

渐近定理的意思是,当n足够大时,π(n)与n / ln(n)的比值逼近于1。

高斯素数定理的意义在于揭示了素数在自然数中的分布特性,为研究素数的性质和素数问题提供了重要的理论基础。

它在数论和分析领域中具有重要的地位,并对数论中的许多研究和证明起到了重要的指导作用。

需要注意的是,高斯素数定理是一个渐近定理,它描述的是当n趋于无穷大时的趋势,而非具体的数值关系。

在具体的数值范围内,素数的分布仍然可能出现一些规律性的偏差和间断性。

1, 2, 3, 4, 5; 6, 7, 8, 9, 10; 11, 12, 13, 14, 15; 16, 17, 18, 19, 20; 21, 22, 23, 24, 25; 26, 27, 28. We call every equal share a complete chunk. The last share is called a broken chunk. Sometimes the last share may also be a complete chunk. For example: The equal share 1, 2, 3, 4, 5; 6, 7, 8, 9, 10; 11, 12, 13, 14, 15 etc are complete chunks. The share 26, 27, 28 is a broken chunk. Observing the given sequence, we find that there is at least one prime every complete chunk. This is not an accidental phenomenon, but an inevitable rule. Remark: 1. the 1th chunk must start with the number 1. 2. May or may not have the prime in the broken chunk. 3. Let Ari denote the set that contains the true elements of the multiples of pi in the r-th chunk, where pi is the i-th prime. Let Bri denote the set that consists of the maximum elements of the multiples of pi in the r-th chunk, where pi is the i-th prime. For instance: Let A11 denote the set that contains the true elements of the multiples of 2, where 2 is the 1-th prime in the 1-th chunk. Let B11 denote the set that contains the maximum elements of the multiples of 2, where 2 is the 1th prime in every chunk. Assume that there are three elements of the multiples of 2 in the set B11 . So
⎡ 28 ⎤ A11 = {2, 4} ⊂ B11 , A11 < B11 = ⎢ ⎥ +1 = 3 . ⎣ 2 ⎦
By the same way, we get

⎡ 28 ⎤ A21 = {6,8,10} = B21 , A21 = B21 = ⎢ ⎥ +1 = 3 . ⎣ 2 ⎦
