The Jensen-Pólya program for various L-functions

Abstract

Pólya proved in 1927 that the Riemann hypothesis is equivalent to the hyperbolicity of all of the Jensen polynomials of degree $d$ and shift $n$ for the Riemann Xi-function. Recently, Griffin, Ono, Rolen, and Zagier proved that for each degree $d\ge 1$ all of the Jensen polynomials for the Riemann Xi-function are hyperbolic except for possibly finitely many $n$. Here we extend their work by showing the same statement is true for suitable $L$-functions. This offers evidence for the generalized Riemann hypothesis.
