报告题目：Large values of quadratic Dirichlet L-functions

报告摘要：The analytic properties of quadratic Dirichlet L-functions play a central role in number theory, owing to their deep connections with quadratic fields and the potential existence of Landau-Siegel zeros. In this talk, we present recent progress on large values of quadratic Dirichlet L-functions in the critical strip, established conditionally on the Generalized Riemann Hypothesis (GRH). We also discuss our conditional results on large values of their derivatives and logarithmic derivatives. This is based on joint work with Haidong Li, and with Ruihua Wang, Weijia Wang, and Hao Zhang.
