Supercomputers and the Riemann Zeta Function
نویسنده
چکیده
The Riemann Hypothesis, which specifies the location of zeros of the Riemann zeta function, and thus describes the behavior of primes, is one of the most famous unsolved problems in mathematics, and extensive efforts have been made over more than a century to check it numerically for large sets of cases. Recently a new algorithm, invented by the speaker and A. Scho . . nhage, has been implemented, and used to compute over 175 million zeros near zero number 1020 . The new algorithm turned out to be over 5 orders of magnitude faster than older methods. The crucial ingredients in it are a rational function evaluation method similar to the GreengardRokhlin gravitational potential evaluation algorithm, the FFT, and band-limited function interpolation. While the only present implementation is on a Cray, the algorithm can easily be parallelized.

A more accurate half-discrete Hardy-Hilbert-type inequality with the best possible constant factor related to the extended Riemann-Zeta function
By the method of weight coefficients, techniques of real analysis and Hermite-Hadamard's inequality, a half-discrete Hardy-Hilbert-type inequality related to the kernel of the hyperbolic cosecant function with the best possible constant factor expressed in terms of the extended Riemann-zeta function is proved. The more accurate equivalent forms, the operator expressions with the norm, the rever...
متن کاملA Discrete Mean Value of the Derivative of the Riemann Zeta Function
In this article we compute a discrete mean value of the derivative of the Riemann zeta function. This mean value will be important for several applications concerning the size of ζ(ρ) where ζ(s) is the Riemann zeta function and ρ is a non-trivial zero of the Riemann zeta function.

متن کاملA Note on Infinite Divisibility of Zeta Distributions
Abstract The Riemann zeta distribution, defined as the one whose characteristic function is the normalised Riemann zeta function, is an interesting example of an infinitely divisible distribution. The infinite divisibility of the distribution has been proved with recourse to the Euler product of the Riemann zeta function. In this paper, we look at multiple zeta-star function, which is a multi-d...
