The extended Riemann hypothesis for abelian extension of the rationals is equivalent to the generalized Riemann hypothesis. The Riemann hypothesis can also be extended to the L-functions of Hecke characters of number fields. The grand Riemann hypothesis extends it to all automorphic zeta functions, such as Mellin transforms of Hecke eigenforms.
In it, broad generalisations of the Riemann zeta function and the L-series for a Dirichlet character are constructed, and their general properties, in most cases still out of reach of proof, are set out in a systematic way. Because of the Euler product formula there is a deep connection between L-functions and the theory of prime numbers.
The Riemann hypothesis is one of the most important conjectures in mathematics. It is a statement about the zeros of the Riemann zeta function . Various geometrical and arithmetical objects can be described by so-called global L -functions , which are formally similar to the Riemann zeta-function.
Riemann's original use of the explicit formula was to give an exact formula for the number of primes less than a given number. To do this, take F(log(y)) to be y 1/2 /log(y) for 0 ≤ y ≤ x and 0 elsewhere. Then the main term of the sum on the right is the number of primes less than x.
The Riemann ξ function is given by = / ()where ζ is the Riemann zeta function.Consider the sequence = ()! [ ()] | =. Li's criterion is then the statement that the Riemann hypothesis is equivalent to the statement that > for every positive integer .
The generalized Riemann hypothesis is the conjecture that all the non-trivial zeros lie on the critical line Re(s) = 1/2. [ 9 ] Up to the possible existence of a Siegel zero , zero-free regions including and beyond the line Re( s ) = 1 similar to that of the Riemann zeta function are known to exist for all Dirichlet L -functions: for example ...
Riesz showed that the Riemann hypothesis is equivalent to the claim that the above is true for any e larger than /. [1] In the same paper, he added a slightly pessimistic note too: « Je ne sais pas encore decider si cette condition facilitera la vérification de l'hypothèse » ("I can't decide if this condition will facilitate the ...
The Riemann zeta function ζ(z) plotted with domain coloring. [1] The pole at = and two zeros on the critical line.. The Riemann zeta function or Euler–Riemann zeta function, denoted by the Greek letter ζ (), is a mathematical function of a complex variable defined as () = = = + + + for >, and its analytic continuation elsewhere.
