Note On Prime Gaps And Very Short Intervals

Assuming the Riemann hypothesis, this article discusses a new elementary argument that seems to prove that the maximal prime gap of a finite sequence of primes p_1, p_2, ..., p_n <= x, satisfies max {p_(n+1) - p_n : p_n <= x} <= c1((logx)^2)/loglogx, c1 > 0 constant. Equivalently, it shows that the very short intervals (x, x + y] contain prime numbers for all y > c2((logx)^2)/loglogx, c2 > 0 constant, and sufficiently large x > 0.Comment: 12 Pages, 1 Table, Improve

An Explicit Formula For The Divisor Function

The details for the construction of an explicit formula for the divisors function d(n) = #{d | n} are formalized in this article. This formula facilitates a unified approach to the investigation of the error terms of the divisor problem and circle problem.Comment: Twenty Eight Pages.

The Error Term of the Summatory Euler Phi Function

A sharper estimate for the summatory Euler phi function $\sum_{n \leq x} \varphi(n)$ is presented in this work. It improves the established estimate in the current mathematical literature. In addition, an estimate for its reciprocal $\sum_{n \leq x} 1/\varphi(n)$ is also determined.Comment: Sixteen Pages. Keywords: Euler Totient Function, Error Term, Arithmetic Functio

Least Prime Primitive Roots

This note presents an upper bound for the least prime primitive roots $g^*(p)$ modulo $p$, a large prime. The current literature has several estimates of the least prime primitive root $g^*(p)$ modulo a prime $p\geq 2$ such as $g^*(p)\ll p^c, c>2.8$. The estimate provided within seems to sharpen this estimate to the smaller estimate $g^*(p)\ll p^{5/\log \log p}$ uniformly for all large primes $p\geq 2$.Comment: Twelve Pages.

Irrationality of the Zeta Constants

A general technique for proving the irrationality of the zeta constants $\zeta(s)$ for odd $s = 2n + 1 \geq 3$ from the known irrationality of the beta constants $L(2n+1)$ is developed in this note. The results on the irrationality of the zeta constants $\zeta(2n)$, where $n\geq 1$, and $\zeta(3)$ are well known, but the results on the irrationality for the zeta constants $\zeta(2n+1)$, where $n \geq 2$, are new, and these results seem to confirm that these constants are irrational numbers.Comment: Twenty Seven Pages.

Deterministic Integer Factorization Algorithms

This note presents a deterministic integer factorization algorithm of running time complexity O(N^(1/6+e)), e > 0. This improves the current performances of deterministic integer factorization algorithms rated at O(N^(1/4+e)) arithmetic operations. Equivalently, given the least (log N)/6 bits of a factor of N = pq, the algorithm factors the integer in polynomial time O(log(N)^c), c > 0 constant.Comment: Six Pages, Improved Version. arXiv admin note: substantial text overlap with arXiv:1003.326

Density of the Values Set of the Tau Function

It is shown that the density of the values set {Tau(n): n <= x} of the nth coefficients Tau(n) of the discriminant function Delta(z), a cusp form of level N = 1 and weight k = 12, has the lower bound #{Tau(n): n > x/log x. The currently known density is #{Tau(n) : n > x^(1/2+o(1)), and the expected density is #{Tau(n) : n <= x} ~ x. The solutions set of the equation Tau(p) = 0 for all primes p => 2, which arises as a singular case of this analysis, is discussed within.Comment: Eleven Pages.
