Title: Tate conjectures for unitary Shimura varieties
Abstract: I will explain how to prove some cases of the Tate conjectures for Shimura varieties using automorphic methods, starting from the pioneering work of Harder, Langlands and Rapoport on Hilbert modular surfaces, and culminating on some recent work (in progress) on Shimura varieties attached to U(n, 1). A large part of this talk is accessible to graduate students.
