Oscillation of Mertens’ product formula

Harold G. Diamond, Janos Pintz (2009)

Journal de Théorie des Nombres de Bordeaux

Mertens’ product formula asserts that p x 1 - 1 p log x e - γ as x . Calculation shows that the right side of the formula exceeds the left side for 2 x 10 8 . It was suggested by Rosser and Schoenfeld that, by analogy with Littlewood’s result on π ( x ) - li x , this and a complementary inequality might change their sense for sufficiently large values of x . We show this to be the case.

Primes in almost all short intervals. II

Danilo Bazzanella (2000)

Bollettino dell'Unione Matematica Italiana

In questo lavoro vengono migliorati i risultati ottenuti in «Primes in Almost All Short Intervals» riguardo la distribuzione dei primi in quasi tutti gli intervalli corti della forma g n , g n + H , con g n funzione reale appartenente ad una ampia classe di funzioni. Il problema viene trattato mettendo in relazione l'insieme eccezionale per la distribuzione dei primi in intervalli nella forma g n , g n + H con l'insieme eccezionale per la formula asintotica ψ x + H - ψ x H  as  x . I risultati presentati vengono quindi ottenuti grazie allo studio...

Remarks on Weil’s quadratic functional in the theory of prime numbers, I

Enrico Bombieri (2000)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

This Memoir studies Weil’s well-known Explicit Formula in the theory of prime numbers and its associated quadratic functional, which is positive semidefinite if and only if the Riemann Hypothesis is true. We prove that this quadratic functional attains its minimum in the unit ball of the L 2 -space of functions with support in a given interval - t , t , and prove again Yoshida’s theorem that it is positive definite if t is sufficiently small. The Fourier transform of the functional gives rise to a quadratic...

Riemann's Hypothesis

Rusev, Peter (2010)

Union of Bulgarian Mathematicians

Riemann’s memoir is devoted to the function π(x) defined as the number of prime numbers less or equal to the real and positive number x. This is really the fact, but the “main role” in it is played by the already mentioned zeta-function.

Some conjectures on the zeros of approximates to the Riemann ≡-function and incomplete gamma functions

James Haglund (2011)

Open Mathematics

Riemann conjectured that all the zeros of the Riemann ≡-function are real, which is now known as the Riemann Hypothesis (RH). In this article we introduce the study of the zeros of the truncated sums ≡N(z) in Riemann’s uniformly convergent infinite series expansion of ≡(z) involving incomplete gamma functions. We conjecture that when the zeros of ≡N(z) in the first quadrant of the complex plane are listed by increasing real part, their imaginary parts are monotone nondecreasing. We show how this...
