Group, Lie and Number Theory Seminar

I will discuss a theory of endoscopy for certain symmetric spaces associated to unitary groups, the main result being the fundamental lemma for the "Lie algebra". This is motivated by the study of certain periods of automorphic forms on unitary groups with applications to arithmetic. After explaining where the fundamental lemma fits into this broader picture, I will describe its proof if time permits. Speaker(s): Spencer Leslie (Duke University)
