Expected Values of $L$-functions Away from the Central Point

Number Theory 2025-02-10 v2

Abstract

We compute the expected value of Dirichlet LL-functions defined over Fq[T]\mathbb{F}_q[T] attached to cubic characters evaluated at an arbitrary s(0,1)s \in (0,1). We find a transition term at the point s=13s=\frac{1}{3}, reminiscent of the transition at the point s=12s=\frac{1}{2} of the bound for the size of an LL-function implied by the Lindel\"of hypothesis. We show that at s=13s=\frac{1}{3}, the expected value matches corresponding statistics of the group of unitary matrices multiplied by a weight function.
