### Prime Numbers Greater Than 3 And Their Gaps Are Handed

Authors: Russell Letkeman
Comments: 3 Pages.

We build a simple recursive model for the prime numbers which at its heart is the prime sieve of Eratosthenes. We also show for prime numbers greater than 3 and their gaps posses a handedness which forbids a large range of possibilities for the choice of intervals in arithmetic progressions.

### A Fundamental Therorem Of Prime Sieving

Authors: Russell Letkeman
Comments: 6 Pages.

We introduce a fundamental theorem of prime sieving (FTPS) and show how it illuminates structure on numbers co-prime to a random product of unique prime numbers. This theorem operates on the transition between the set of numbers co-prime to any product of unique prime numbers and the new set when another prime number is introduced in the product.

### Fermat Primes to Become Criterion for the Constructibility of Regular 2^k-Sided Polygons

Authors: Pingyuan Zhou
Comments: 9 Pages. Author gives an argument for indirect connections between Fermat primes and regular 2^k-sided polygons to make Gauss-Wantzel theorem have general sense in implying connections between Fermat primes and all constructible polygons.

Abstract: Gauss-Wantzel theorem shows that regular n-sided polygons, whose number of sides contains a(distrinct) Fermat prime(s) as odd prime factor(s) of n or number of sides is power of 2, are all constructible with compass and straightedge. But of these caces, the constructibility of all regular 2^k-sided polygons is not related to Fermat primes. We discover the number of so-called root Mersenne primes Mp for p4 ( though there are no known Fermat primes Fk for k>4 ) then the constructibility of all regular 2^k-sided polygons can be indirectly explained by Fermat primes as criterion. Thus there exist direct or indirect connections between Fermat primes and all constructible regular polygons according to the theorem.

### Legendre’s Conjecture

Authors: Réjean Labrie
Comments: 7 Pages.

This article introduced in July 2014 was intended as a demonstration of the existence of at least one prime number between two consecutive squares. I see now that the lemma is partially wrong, so the demonstration no longer holds.

### The Strong Finiteness of Double Mersenne Primes and the Infinity of Root Mersenne Primes and Near-square Primes of Mersenne Primes

Authors: Pingyuan Zhou
Comments: 14 Pages. Author presents the strong finiteness of double Mersenne primes and the infinity of root Mersenne primes and near-square primes of Mersenne primes by generalizing conjecture about primality of Mersenne number.

Abstract: In this paper we present the strong finiteness of double Mersenne primes to be a subset of Mersenne primes, the infinity of so-called root Mersenne primes to be also a subset of Mersenne primes and the infinity of so-called near-square primes of Mersenne primes by generalizing our previous conjecture about primality of Mersenne number. These results and our previous results about the strong finiteness of Fermat, double Fermat and Catalan-type Fermat primes  give an elementary but complete understanding for the infinity or the strong finiteness of some prime number sequences of the form 2^x±1, which all have a corresponding original continuous natural ( prime ) number sequence. It is interesting that the generalization to near-square primes of Mersenne primes Wp=2(Mp)^2-1 has brought us positive result.

### Odd Perfect Number is 36k+9

Authors: Isaac Mor
Comments: 3 Pages.

Odd Perfect Number = 36k+9 In 1953, Jacques Touchard proved that an odd perfect number must be of the form 12k + 1 or 36k + 9. (Judy A. Holdener discovered a simpler proof of the theorem of Touchard in 2002) if I am right then I (isaac mor lol) just showed that an odd perfect number must be of the form 36k+9 (19 july 2014)

### The Strong Finiteness of Fermat, Double Fermat and Catalan-type Fermat Primes

Authors: Pingyuan Zhou
Comments: 9 Pages. In this paper, author presents the strong finiteness of Fermat primes, double Fermat primes and Catalan-type Fermat primes by generalizing previous conjecture about primality of Fermat numbers to double Fermat and Catalan-type Fermat numbers.

Abstract: In this paper we present that so-called double Fermat numbers are an infinite subset of well-known Fermat numbers and so-called Catalan-type Fermat numbers are also an infinite subset of Fermat numbers as well as double Fermat primes and Catalan-type Fermat primes are all strongly finite as Fermat primes do. From it we get the same result that composite Fermat numbers, composite double Fermat numbers and composite Catalan-type Fermat numbers are all infinite.

### A Conjecture on Near-square Prime Number Sequence of Mersenne Primes

Authors: Pingyuan Zhou
Comments: 4 Pages. Aothor presents a near-sguare number sequence of all Mersenne primes, which seems to be an accptable awy in searching for larger primes by known Mersenne primes themselves than the largest known Mersenne prime M57885161.

Abstract: In this paper we present a conjecture that there is a near-square prime number sequence of Mersenne primes to arise from the near-square number sequence Wp=2(Mp)^2-1 generated from all Mersenne primes Mp, in which every term is larger prime number than corresponding perfect number. The conjecture has been verified for the first few prime terms in the near-square prime number sequence and we may expect appearing of near-square prime numbers of some known Mersenne primes with large p-values will become larger primes to be searched than the largest known Mersenne prime M57885161.

### On the Existence of Infinitely Many Mersenne Primes and Finitely Many Fermat Primes

Authors: Pingyuan Zhou
Comments: 8 Pages. Author presents two symmetric conjectures related to Mersenne and Fermat primes themselves. It may imply that Mersenne primes are infinite but Fermat primes are finite.

Abstract: From existence of the intersection of the set of Mersenne primes and the set of Fermat primes being a set to contain only one element 3 to be the first Mersenne prime and also the first Fermat prime we fell there are connections between Mersenne and Fermat primes. In this paper, it is presented that two symmetric conjectures related to Mersenne and Fermat primes themselves will lead us to expect Mersenne primes to be infinite but Fermat primes to be finite.

### On Goldbach Conjecture

Authors: Dhananjay P. Mehendale
Comments: 9 pages.

Goldbach conjecture asserts that every even integer greater than 4 is sum of two odd primes. Stated in a letter to Leonard Euler by Christian Goldbach in 1842, this is still an enduring unsolved problem. In this paper we develop a new simple strategy to settle this most easy to state problem which has baffled mathematical community for so long. We show that the existence of two odd primes for every even number greater than 4 to express it as their sum follows from the well known Chinese remainder theorem. We develop a method to actually determine a pair (and subsequently all pairs) of primes for any given even number to express it as their sum. For proof sake we will be using an easy equivalent of Goldbach conjecture. This easy equivalent leads to a congruence system and existence of solution for this congruence system is assured by Chinese remainder theorem. Each such solution actually provides a pair of primes to express given even number as their sum. We also discuss how twin prime conjecture follows from existence of certain x as a solution of certain congruence system.

### Structural Similarity Between the Ordered Pairs of Primes and Non-Primes

Authors: Taekyoon park, Yeonsoo Kim, Jong Min Lee
Comments: 10 Pages. To prove Goldbach's conjecture, we developed our own dynamic model for Goldbach partition. This is the first step of our study.

There have been various approach to prove Goldbach's conjecture using analytical number theory. We go back to the starting point of this famous probelm and are able to show that the number of Goldbach partition is related to that of ordered pairs of non-primes. This proof is based on the world's first dynamic model of primes and can be a key to identify the structure of prime numbers.

### The Simple Mersenne Conjecture

Authors: Pingyuan Zhou
Comments: 9 Pages. Author presents a conjecture called the simple Mersenne conjecture, which may imply there are no more double Mersenne primes.

Abstract: In this paper we conjecture that there is no Mersenne number M(p)=2^p-1 to be prime for p=2^k±1,±3 when k>7, where p is positive integer and k is natural number. It is called the simple Mersenne conjecture and holds till p≤30402457 from status of this conjecture. If the conjecture is true then there are no more double Mersenne primes besides known double Mersenne primes MM(2), MM(3), MM(5), MM(7).

### A Formula Which Conducts to Primes or to a Type of Composites that Could Form a Class Themselves

Authors: Marius Coman
Comments: 2 Pages.

In this paper I present a very simple formula which conducts often to primes or composites with very few prime factors; for instance, for the first 27 consecutive values introduced as “input” in this formula were obtained 10 primes, 4 squares of primes and 12 semiprimes; just 2 from the numbers obtained have three prime factors; but the most interesting thing is that the composites obtained have a special property that make them form a class of numbers themselves.
