The fourth moment of quadratic Dirichlet $L$-functions

Number Theory 2020-07-29 v3

Abstract

We study the fourth moment of quadratic Dirichlet LL-functions at s=12s= \frac{1}{2}. We show an asymptotic formula under the generalized Riemann hypothesis, and obtain a precise lower bound unconditionally. The proofs of these results follow closely arguments of Soundararajan and Young [19] and Soundararajan [17].
