On the location of the zero-free half-plane of a random Epstein zeta function

Artikel i vetenskaplig tidskrift, 2018

In this note we study, for a random lattice L of large dimension n, the supremum of the real parts of the zeros of the Epstein zeta function En(L, s) and prove that this random variable scaled by n- 1has a limit distribution, which we give explicitly. This limit distribution is studied in some detail; in particular we give an explicit formula for its distribution function. Furthermore, we obtain a limit distribution for the frequency of zeros of En(L, s) in vertical strips contained in the half-plane Rs>n2.
