Many statements equivalent to the Riemann hypothesis have been found, though so far none of them have led to much progress in proving or disproving it.

Commentarii academiae scientiarum Petropolitanae 9,pp. Leonhard Euler already considered this series in the s for real values of s, in conjunction with his solution to the Basel problem.

He showed that this in turn would imply that the Riemann hypothesis is true. Most zeros lie close to the critical line. His formula was given in terms of the related function. Ron Dell rated ipotesu did not like it Jan 23, The Riemann hypothesis is equivalent to several statements showing that the terms of the Farey sequence are fairly regular. Ford gave a version with explicit numerical constants: This zero-free region has been enlarged by several authors using methods such as Vinogradov’s mean-value theorem.

Schoenfeld also showed that the Riemann hypothesis implies. Pablo rated it did not like it Oct 02, Books by Marcus du Sautoy.

Indeed, Trudgian showed that both Gram’s law and Rosser’s rule fail in a positive proportion of cases. Another prime page by Chris K. To verify the Riemann hypothesis up to a given imaginary part T of the zeros, one also has to check that there are no further zeros off the line in this region.

The other terms fi correspond to zeros: From Wikipedia, the free encyclopedia. Number Theory This is a case in which even the best bound that can be proved using the Riemann hypothesis is far weaker than what seems true: The determinant of the order n Redheffer matrix is equal to M nso the Riemann hypothesis can also be stated as a condition on the growth of these determinants.

Some riemajn for this idea comes from several analogues of the Riemann zeta functions whose zeros correspond to eigenvalues of some operator: This requires almost no extra work because the sign of Z at Gram points is already known from finding the zeros, and is still the usual method used. Related is Li’s criteriona statement ipotedi the positivity of a certain sequence of numbers is equivalent to the Riemann hypothesis.


Several results first proved using the generalized Riemann hypothesis were later given unconditional proofs without using it, though these were usually much harder. Odlyzko showed that this is supported by large scale numerical calculations of these correlation functions. The method of proof is interesting, in that the inequality is shown first under the assumption that the Riemann hypothesis is true, secondly under the contrary assumption.

This was a key step in their first proofs of the prime number theorem. New Series5 1: Some of these ideas are elaborated in Lapidus Iootesi ask other readers questions about L’enigma dei numeri primiplease sign up.

Analytischer Teil”, Mathematische Zeitschrift19 1: A precise version of Koch’s result, due to Schoenfeldsays that the Riemann hypothesis implies. Marym Hashim rated it did not like it Jul 13, Really enjoyed Fermat’s Last Enigma by Singh, and was probably looking for another similar book.

The functional equation also implies that the zeta function has no zeros with negative real part other than the trivial zeros, so xi non-trivial zeros lie in the critical strip where s has real part between 0 and 1. Contrary to this, in dimension two work of Ivan Fesenko on two-dimensional generalisation of Tate’s riemmann includes an integral representation of a zeta integral closely related to the zeta function.


A multiple zero would cause problems for the zero finding algorithms, which depend on finding sign changes between zeros. Riemann’s explicit formula for the number of primes less than a given number in terms of a sum over the zeros of the Riemann zeta function says that the magnitude of the oscillations of primes around their expected position is controlled by the real parts of the zeros of the zeta function.

A regular finite graph is a Ramanujan grapha mathematical model of efficient communication networks, if and only if its Ihara zeta function satisfies the analogue of the Riemann hypothesis as was pointed out by T. Tahu rated it did not like it Sep 13, The Selberg trace formula is the analogue for these functions of the explicit formulas in prime number theory. Nicolas proved Ribenboimp. Another way to generalize Euler’s sum is to leave the field of rational numbers, and replace the denominators with the norms of the non-zero ideals special sets of elements in a finite field extention of the rationals K called a number field.

This is the sum of a large but well understood term.
