Hardy–Littlewood zeta-function conjectures

From Wikipedia, the free encyclopedia

In mathematics, the Hardy–Littlewood zeta-function conjectures, named after Godfrey Harold Hardy and John Edensor Littlewood, are two conjectures concerning the distances between zeros and the density of zeros of the Riemann zeta function.

Conjectures[]

In 1914 Godfrey Harold Hardy proved[1] that the Riemann zeta function has infinitely many real zeros.

Let be the total number of real zeros, be the total number of zeros of odd order of the function , lying on the interval .

Hardy and Littlewood claimed[2] two conjectures. These conjectures – on the distance between real zeros of and on the density of zeros of on intervals for sufficiently great , and with as less as possible value of , where is an arbitrarily small number – open two new directions in the investigation of the Riemann zeta function.

1. For any there exists such that for and the interval contains a zero of odd order of the function .

2. For any there exist and , such that for and the inequality is true.

Status[]

In 1942 Atle Selberg studied the problem 2 and proved that for any there exists such and , such that for and the inequality is true.

In his turn, Selberg made his conjecture[3] that it's possible to decrease the value of the exponent for which was proved 42 years later by A.A. Karatsuba.[4]
