Confirmation of Riemann Hypothesis Allows the Calculation of the 19th and 21st Mills' Primes

Authors: Thomas Pierre Nicolas Jean Brouard
Comments: 3 Pages.

Using the η function, we show that the real part of the non-trivial zeros of the Riemann zeta function is 1/2. Then, we calculate two big primes using the Riemann hypothesis as true. These two big primes have respectively more than one hundred millions digits and more than one billion digits.

Primes Obtained Concatenating the Numbers S(p)-D(k), Where S(p) is the Sum of Digits of a Prime P and D(1),...,d(k) the Digits of P

Authors: Marius Coman
Comments: 2 Pages.

In this paper I make the following conjecture: There exist an infinity of primes p having the property that concatenating s(p) – d(1) with s(p) – d(2) and repeatedly up to s(p) – d(k), where s(p) is the sum of digits of p and d(1),...,d(k) are the digits of p, is obtained a prime q. Example: such prime p is 127 because concatenating 9 (= 10 – 1) with 8 (= 10 – 2) and with 3 (= 10 – 7) is obtained a prime q = 983.

A New Sufficient Condition by Euler Function for Riemann Hypothesis

Authors: Choe Ryong Gil
Comments: 12 pages, 2 tables

The aim of this paper is to show a new sufficient condition (NSC) by the Euler function for the Riemann hypothesis and its possibility. We build the NSC for any natural numbers ≥ 2 from well-known Robin theorem, and prove that the NSC holds for all odd and some even numbers while, the NSC holds for any even numbers under a certain condition, which would be called the condition (d).

An Upper Bound for Error Term of Mertens' Formula

Authors: Choe Ryong Gil
Comments: 27 pages, 6 tables

In this paper, it is obtained a new estimate for the error term E(t) of the Mertens' formula sum_{p≤t}{p^{-1}}=loglogt+b+E(t), where t>1 is a real number, p is the prime number and b is the well-known Mertens' constant. We , first, provide an upper bound, not a lower bound, of E(p) for any prime number p≥3 and, next, give one in the form as E(t)<logt/√t for any real number t≥3. This is an essential improvement of already known results. Such estimate is very effective in the study of the distribution of the prime numbers.

On Fermat's Last Theorem - An Elementary Approach

Authors: Gang Li
Comments: 14 Pages.

An attempt of using elementary approach to prove Fermat's last theorem (FLT) is given. For infinitely many prime numbers, Case I of the FLT can be proved using this approach. Furthermore, if a conjecture proposed in this paper is true (k-3 conjecture), then case I of the FLT is proved for all prime numbers. For case II of the FLT, a constraint for possible solutions is obtained.

Comments: 13 pages, 5 figures, arXiv:1603.02468, Keywords: Power function, Monomial, Polynomial, Power series, Finite difference, Derivative, Differential calculus, Differentiation, Binomial coefficient, Newton's Binomial Theorem, Exponential function

In this paper described numerical expansion of natural-valued power function $x^n$, in point $x=x_0$ where $n, \ x_0$ - natural numbers. Applying numerical methods, that is calculus of finite differences, namely, discrete case of Binomial expansion is reached. Received results were compared with solutions according to Newton’s Binomial theorem and MacMillan Double Binomial sum. Additionally, in section 4 exponential function’s $e^x$ representation is shown. In Application 3 generalized calculus of finite differences, based on expression (1.9) is shown.

Primes Obtained Concatenating P∙q∙r-P with P∙q∙r-Q with P∙q∙r-R Then with P∙q∙r Where p, q, R Primes of the Form 6k+1

Authors: Marius Coman
Comments: 2 Pages.

This paper is inspired by one of my previous papers, namely “Large primes obtained concatenating the numbers P - d(k) where d(k) are the prime factors of the Poulet number P”, where I conjectured that there are an infinity of primes which can be obtained concatenating the numbers P - d(1); P - d(2); ...; P – d(k); P, where d(1), ..., d(k) are the prime factors of the Poulet number P. Because some of these Poulet numbers are 3-Poulet numbers of the form (6k + 1)*(6h + 1)*(6j + 1) I extend in this paper that idea conjecturing that for any prime p of the form 6k + 1 there exist an infinity of pairs of primes [q, r], of the form 6h + 1 and 6j + 1, such that the number obtained concatenating p*q*r – p with p*q*r – q with p*q*r – r then with p*q*r is prime.

Large Primes Obtained Concatenating the Numbers P-D(k) Where D(k) Are the Prime Factors of the Poulet Number P

Authors: Marius Coman
Comments: 2 Pages.

In this paper I conjecture that there are an infinity of primes which can be obtained concatenating the numbers P - d(1); P - d(2); ...; P – d(k); P, where d(1), ..., d(k) are the prime factors of the Poulet number P. Example: using the sign “//” with the meaning “concatenated to”, for the Poulet number 129921 (= 3*11*31*127), the number (129921 – 3)//(129921 – 11)//(129921 – 31)//(129921 – 127)//129921 = 129918129910129890129794129921 is prime. Note that such primes are obtained for 10 from the first 90 Poulet numbers!

Primes Obtained Concatenating the Numbers 30-D(k) Where D(1),...,d(k) Are the Digits of a Square of a Prime

Authors: Marius Coman
Comments: 2 Pages.

In this paper I make the following observation: for many squares of primes (I conjecture that for an infinity of them) the numbers obtained concatenating 30 – d(1), 30 – d(2),..., 30 – d(k), where d(1),..., d(k) are the digits of a square of a prime, are primes. Example: for 1369 (= 37^2) the number obtained concatenating 29 = 30 – 1 with 27 = 30 – 3 with 24 = 30 – 6 with 21 = 30 – 9, i.e. the number 29272421, is prime. Note that for 35 from the first 200 squares of primes the numbers obtained this way are primes!
