Title: Tamagawa Numbers via Nonabelian Poincare Duality (Ordway Lecture III)

Abstract: In this lecture, I'll describe some joint work with Dennis Gaitsgory, using an algebro-geometric analogue of nonabelian Poincare duality to study the function field analogue of Weil's conjecture on Tamagawa numbers of algebraic groups.
