Abstract

We describe a new method to obtain weak subconvexity bounds for L-functions with mild hypotheses on the size of the Dirichlet coefficients. We verify these hypotheses for all automorphic L-functions and (with mild restrictions) the Rankin-Selberg Lfunctions attached to two automorphic representations. The proof relies on a new unconditional log-free zero density estimate for Rankin-Selberg L-functions.
