Abstract

We establish a central limit theorem for the central values of Dirichlet L-functions with respect to a weighted measure on the set of primitive characters modulo q as q→∞. Under the Generalized Riemann Hypothesis (GRH), we also prove a weighted central limit theorem for the joint distribution of the central L-values corresponding to twists of two distinct primitive Hecke eigenforms. As applications, we obtain (under GRH) positive proportions of twists for which the central L-values simultaneously grow or shrink with q as well as a positive proportion of twists for which linear combinations of the central L-values are nonzero.
