On the Zeros of the Ramanujan Τ-dirichlet Series in the Critical Strip

نویسنده

چکیده

We describe computations which show that each of the first 12069 zeros of the Ramanujan τ -Dirichlet series of the form σ + it in the region 0 < t < 6397 is simple and lies on the line σ = 6. The failures of Gram’s law in this region are also noted. The first 5018 zeros and 2228 successive zeros beginning with the 20001st zero are also calculated. The distribution of the normalized spacing of the zeros is examined and it appears to be that of the eigenvalues of random matrices. These comptuations are done with a BerryKeating formula for the τ -Dirichlet series and evaluated using MathematicaTM.

On the Ratio of the Modulus of Dirichlet Eta Function Values of Critical Line Symmetrical Arguments and the Riemann Hypothesis

ABSTRACT. Said Sn(s) the nth partial sum of the Dirichlet η function, Rn(s) the corresponding remainder term, and ρ = 2 +α + it , τ = 1 2 −α + it , a pair of arguments symmetrical with respect to the critical line, and restricting the following considerations to the domain corresponding to the interior of the critical strip, it is shown that proving the sequence of functions {|Sn(ρ)|/|Sn(τ)|} t...

On a Secant Dirichlet Series and Eichler Integrals of Eisenstein Series

We consider, for even s, the secant Dirichlet series ψs(τ) = ∑∞ n=1 sec(πnτ) ns , recently introduced and studied by Laĺın, Rodrigue and Rogers. In particular, we show, as conjectured and partially proven by Laĺın, Rodrigue and Rogers, that the values ψ2m( √ r), with r > 0 rational, are rational multiples of π2m. We then put the properties of the secant Dirichlet series into context by showing ...

Special values of trigonometric Dirichlet series and Eichler integrals

We provide a general theorem for evaluating trigonometric Dirichlet series of the form ∑ n>1 f(πnτ) ns , where f is an arbitrary product of the elementary trigonometric functions, τ a real quadratic irrationality and s an integer of the appropriate parity. This unifies a number of evaluations considered by many authors, including Lerch, Ramanujan and Berndt. Our approach is based on relating th...
