Four Unusual Conjectures on Primes Involving Egyptian Fractions

Authors: Marius Coman
Comments: 2 Pages.

In this paper I make four conjectures on primes, conjectures which involve the sums of distinct unit fractions such as 1/p(1) + 1/p(2) + (...), where p(1), p(2), (...) are distinct primes, more specifically the periods of the rational numbers which are the results of the sums mentioned above.

Three Formulas that Generate Easily Certain Types of Triplets of Primes

Authors: Marius Coman
Comments: 2 Pages.

In this paper I present three formulas, each of them with the following property: starting from a given prime p, are obtained in many cases two other primes, q and r. I met the triplets of primes [p, q, r] obtained with these formulas in the study of Carmichael numbers; the three primes mentioned are often the three prime factors of a 3-Carmichael number.

Proof that an Infinite Number of Mersenne Prime Numbers Exit

Authors: Stephen Marshall
Comments: 11 Pages.

This paper presents a complete and exhaustive proof of the infinitude of Mersenne prime numbers. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we prove that if p > 1 and d > 0 are integers, that p and p + d are both primes if and only if for integer n (see reference 1 and 2): n=(p-1)!(1/p+(-1)dd!/(p + d))+1/p+ 1/(p+d) We use this proof for d = 2p(k+m) - 2p(k) to prove the infinitude of Mersenne prime numbers.

An Amazing Formula for Producing Big Primes Based on the Numbers 25 and 906304

Authors: Marius Coman
Comments: 3 Pages.

In this paper I present a formula for generating big primes and products of very few primes, based on the numbers 25 and 906304, formula equally extremely interesting and extremely simple, id est 25^n + 906304. This formula produces for n from 1 to 30 (and for n = 30 is obtained a number p with not less than 42 digits) only primes or products of maximum four prime factors.

Proof That an Infinite Number of Sophie Germain Primes Exist

Authors: Stephen Marshall
Comments: 6 Pages.

In number theory, a prime number p is a Sophie Germain prime if 2p + 1 is also prime. For example, 29 is a Sophie Germain prime because it is a prime and 2 × 29 + 1 = 59, and 59 is also a prime number. These numbers are named after French mathematician Marie-Sophie Germain. We shall prove that there are an infinite number of Sophie Germain primes.

Proof of Infinite Number of Triplet Primes

Authors: Stephen Marshall
Comments: 12 Pages.

This paper presents a complete and exhaustive proof that an Infinite Number of Triplet Primes exist. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we prove that if p > 1 and d > 0 are integers, that p and p + d are both primes if and only if for integer n (see reference 1 and 2): n =(p−1)!(1/p+(−1)d(d!)/(p + d)+ 1/(p+1)+ 1/(p+d) We use this proof and Euclid logic to prove only an infinite number of Triplet Primes exist. However we shall begin by assuming that a finite number of Triplet Primes exist, we shall prove a contradiction to the assumption of a finite number, which will prove that an infinite number of Triplet Primes exist.

The Sequence of the Primes

Authors: Anibal Fernando Barral
Comments: 24 Pages.

In mathematics, a prime number is a natural number that is divisible only by 1 and itself. For centuries, the search for an algorithm that could generate the sequence of these numbers became a mystery. Perhaps the problem arises at the beginning of the enterprise, that is, the search for a single algorithm. I noticed that all the primes without exception increased by one unit in some cases, or decreased by one unit in the other cases result in a multiple of 6 (six) Example: 5+1=6 ; 7-1=6 ; 11+1=12 ; 13-1=12 ; 17+1=18 ; 19-1=18 ; 23+1=24 ; 29+1=30 ; 31-1=30 ; 37-1=36 ; 41+1=42 ; 43-1=42 ; 47+1=48 ; and so on. Then I thought of making it easier to split the problem solving both cases. So are passed to assume the presence of # 2 complementary families of primes. To the number 1000, I worked by hand, a job with some effort but great satisfaction. At this point my algorithms were reliable, but I needed another test. To get to number 60,000 I leaned in a computational program, which compiled a dear friend. I would have liked to get up to 1,000,000 but the limit of 60,000 has been imposed by the processing time of the data. At this point I had no more doubts about the reliability of my algorithms that are developed in continuation.

Comments on Recent Papers by S. Marshall Claiming Proofs of Several Conjectures in Number Theory

Authors: Matthias Lesch
Comments: 3 Pages.

In a recent series of preprints S. Marshall claims to give proofs of several famous conjectures in number theory, among them the twin prime conjecture and Goldbach’s conjecture. A claimed proof of Beal’s conjecture would even imply an elemen- tary proof of Fermat’s Last Theorem. It is the purpose of this note to point out serious errors. It is the opinion of this author that it is safe to say that the claims of the above mentioned papers are lacking any basis.

Generalized Expansions of Real Numbers

Authors: Simon Plouffe
Comments: 38 Pages.

I present here a collection of algorithms that permits the expansion into a finite series or sequence from a real number x∈ R, the precision used is 64 decimal digits. The collection of mathematical constants was taken from my own collection and theses sources [1]-[6][9][10]. The goal of this experiment is to find a closed form of the sequence generated by the algorithm. Some new results are presented.

On a Strange Class of Algebraic Numbers

Authors: Simon Plouffe
Comments: 9 Pages. The abstract in english and the main text in french

The iteration formula Z_(n+1)=Z_n^2+c of Mandelbrot will give an algebraic number of degree 4 when it converges most of the time. If we take a good look at some of these algebraic numbers: some of them have a very persistent pattern in their binary expansion. La formule d’itération de Mandelbrot Z_(n+1)=Z_n^2+c converge vers un nombre algébrique de degré 4 si c est un rationnel simple. Mais en regardant de près certains nombres algébriques en binaire on voit apparaître un motif assez évident et très persistant.

On the Values of the Function Zeta and Gamma

Authors: Simon Plouffe
Comments: 13 Pages. The abstract in english and the main text in french

An analysis of the function 1/π Arg ζ((1/2)+in) is presented. This analysis permits to find a general expression for that function using elementary functions of floor and fractional part. These formulas bring light to a remark from Freeman Dyson which relates the values of the ζfunction to quasi-crystals. We find these same values for another function which is very similar, namely 1/π Arg Γ((1/4)+in/2). These 2 sets of formula have a definite pattern, the n’th term is related to values like π,ln⁡(π),ln⁡(2),…,log⁡(p), where p is a prime number. The coefficients are closed related to a certain sequence of numbers which counts the number of 0’s from the right in the binary representation of n. These approximations are regular enough to deduce an asymptotic and precise formula. All results presented here are empirical.

Goldbach's Conjecture. Demonstration by Analysis of Arithmetic Progressions

Authors: Ramón Ruiz
Comments: 34 Pages. This research is based on an approach developed solely to demonstrate the binary Goldbach Conjecture and the Twin Primes Conjecture.

Goldbach's Conjecture statement: “Every even integer greater than 2 can be expressed as the sum of two primes”. Initially, to prove this conjecture, we can form two arithmetic sequences (A and B) different for each even number, with all the natural numbers that can be primes, that can added, in pairs, result in the corresponding even number. By analyzing the pairing process, in general, between all non-prime numbers of sequence A with terms of sequence B, or vice versa, to obtain the even number, we note that some pairs of primes are always formed. This allow us to develop a non-probabilistic formula to calculate the approximate number of pairs of primes that meet the conjecture for an even number x. The result of this formula is always equal or greater than 1, and it tends to infinite when x tends to infinite, which allow us to confirm that Goldbach's Conjecture is true. The prime numbers theorem by Carl Friedrich Gauss, the prime numbers theorem in arithmetic progressions and some axioms have been used to complete this investigation.

Twin Primes Conjecture. Demonstration by Analysis of Arithmetic Progressions.

Authors: Ramón Ruiz
Comments: 24 Pages. This research is based on an approach developed solely to demonstrate the Twin Primes Conjecture and the binary Goldbach Conjecture.

Twin Primes Conjecture statement: “There are infinitely many primes p such that (p + 2) is also prime”. Initially, to prove this conjecture, we can form two arithmetic sequences (A and B) with all the natural numbers, lesser than a number x, that can be primes and being each term of sequence B equal to its partner of sequence A plus 2. By analyzing the pairing process, in general, between all non-prime numbers of sequence A with terms of sequence B, or vice versa, we note that some pairs of primes are always formed. This allow us to develop a non-probabilistic formula to calculate the approximate number of pairs of primes, p and (p + 2), that are lesser than x. The result of this formula tends to infinite when x tends to infinite, which allow us to confirm that the Twin Primes Conjecture is true. The prime numbers theorem by Carl Friedrich Gauss, the prime numbers theorem in arithmetic progressions and some axioms have been used to complete this investigation.

Proofs of Polignac Prime Conjecture, Goldbach Conjecture, Twin Prime Conjecture, Cousin Prime Conjecture, and Sexy Prime Conjecture

Authors: Stephen Marshall
Comments: 10 Pages. This is an updated proof by the author.

This paper presents a complete and exhaustive proof of the Polignac Prime Conjecture. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we use a proof found in Reference 1, that if p > 1 and d > 0 are integers, that p and p + d are both primes if and only if for integer n: n = (p−1)!(1/p+(−1)d(d!)/(p + d)+ 1/(p+1)+ 1/(p+d) We use this proof for d = 2k to prove the infinitude of Polignac prime numbers. The author would like to give many thanks to the authors of 1001 Problems in Classical Number Theory, Jean-Marie De Koninck and Armel Mercier, 2004, Exercise Number 161 (see Reference 1). The proof provided in Exercise 6 is the key to making this paper on the Polignac Prime Conjecture possible. Additionally, our proof of the Polignac Prime Conjecture leads to proofs of several other significant number theory conjectures such as the Goldbach Conjecture, Twin Prime Conjecture, Cousin Prime Conjecture, and Sexy Prime Conjecture. Our proof of Polignac’s Prime Conjecture provides significant accomplishments to Number Theory, yielding proofs to several conjectures in number theory that has gone unproven for hundreds of years.

Proof of Beal’s Conjecture

Authors: Stephen Marshall
Comments: 7 Pages. Updated some wording

This paper presents a complete and exhaustive proof of the Beal Conjecture. The approach to this proof uses the Fundamental Theorem of Arithmetic as the basis for the proof of the Beal Conjecture. The Fundamental Theorem of Arithmetic states that every number greater than 1 is either prime itself or is unique product of prime numbers. The prime factorization of every number greater than 1 is used throughout every section of the proof of the Beal Conjecture. Without the Fundamental Theorem of Arithmetic, this approach to proving the Beal Conjecture would not be possible.

Authors: Oh Jung Uk
Comments: 16 Pages. I don't know how to show abstract well

For Mersenne prime of 2^(6n+1)-1 type, if a Mersenne prime is 2^(6p+1)-1, just next Mersenne prime is 2^(6x+1)-1 then the following equation is satisfied. x =p+3/2+1/2 ∑_(k=p+1)^x▒〖(πβ(2^(6k+1)-1)+1)/(πβ(2^(6k+1)-1)-1)+1/π ∑_(k=p+1)^x▒∑_(m=1)^∞▒sin⁡((2mπ^2 β(2^(6k+1)-1))/(πβ(2^(6k+1)-1)-1))/m〗 where,β(2^(6k+1)-1)=τ(2^(6k+1)-1)-2,… Mersenne prime of 2^(6n-1)-1 type is omitted in abstract.

Study of Fermat Number

Authors: Oh Jung Uk
Comments: 12 Pages. I don't know how to show abstract well

A number of 6n-1 type is not odd perfect number, Fermat number is not also odd perfect number. And, if Fermat number is composite number then Fermat number is factorized as below when n is odd number,2^(2^n )+1=(2^(n+1) (3k+1)+1)(2^(n+1) (3m)+1) when n is even number,2^(2^n )+1=(2^(n+1) ((3k+1)/2)+1)(2^(n+1) (3m)+1) And, all Fermat number for n≥5 is composite number.

The Formula of π(N)

Authors: Oh Jung Uk
Comments: 34 Pages. I don't know how I can fix the abstract

The formula of prime-counting function π(N=6n+3) is described below. π(N=6n+3)=2n+2-2/3 ∑_(k=1)^n▒{πβ(6k-1)/(πβ(6k-1)-1)+πβ(6k+1)/(πβ(6k+1)-1)} -2/3π ∑_(k=1)^n▒∑_(m=1)^∞▒{(sin⁡((2mπ^2 β(6k-1))/(πβ(6k-1)-1))+sin⁡((2mπ^2 β(6k+1))/(πβ(6k+1)-1)))/m} where,β(6k-1)=τ(6k-1)-2,β(6k+1)=τ(6k+1)-2,…

Co-Prime Gap N-Tuples that Sum to a Number and Other Algebraic Forms

Authors: Russell Letkeman
Comments: 4 Pages.

We study the spacings of numbers co-prime to an even consecutive product of primes, P_m\# and its structure exposed by the fundamental theorem of prime sieving (FTPS). We extend this to prove some parts of the Hardy-Littlewood general prime density conjecture for all finite multiplicative groups modulo a primorial. We then use the FTPS to prove such groups have gap spacings which form arithmetic progressions as long as we wish. We also establish their densities and provide prescriptions to find them.

Two Conjectures, on the Primes of the Form 6k Plus 1 Respectively of the Form 6k Minus 1

Authors: Marius Coman
Comments: 2 Pages.

In this paper I make two conjectures, one about how could be expressed a prime of the form 6k + 1 and one about how could be expressed a prime of the form 6k – 1.
