The effect of repeated differentiation on $L$-functions

Number Theory 2018-05-15 v2

Abstract

We show that under repeated differentiation, the zeros of the Selberg Ξ\Xi-function become more evenly spaced out, but with some scaling towards the origin. We do this by showing the high derivatives of the Ξ\Xi-function converge to the cosine function, and this is achieved by expressing a product of Gamma functions as a single Fourier transform.
