Title: Nonvanishing of L-functions
Abstract: L-functions are
important and interesting analytic objects in number theory. The
special values of L-functions and their derivatives at the central
point of the critical strip are connected with several branches of
mathematics. In this talk, we will focus the nonvanishing of such
values and will explain how to use the method of moments and the
mollification method to obtain strong nonvanishing results for
L-functions in various families of automorphic forms. If time permits,
we will mention some applications of the nonvanishing results.
