Lower bounds for small fractional moments of Dirichlet $L$-functions

Number Theory 2012-01-30 v1

Abstract

We prove a lower bound of the correct order of magnitude in the conductor aspect for small rational moments of Drichlet LL-functions. Such bounds require new techniques, which is visible from the relationship to non-vanishing results for L(1/2,χ)L(1/2, \chi).
