+Lecture 1 : On generalized Hitchin fibration and orbital integrals
Abstract: The original Hitchin fibration is a formidable geometric tool to study orbital integrals in Lie algebras, in particular to prove the Langlands-Shelstad fundamental lemma for Lie algebras. In this lecture, I present generalized Hitchin fibrations to study other type of orbital integrals.
+Lecture 2 : On stable Bernstein centers and cocenters in relation to Langlands functoriality
Abstract: We examine Langlands's functoriality and stable transfer from a new point of view via the stable center and cocenter. (joint work with Zhilin Luo)
+Lecture 3 : Character sheaves on loop Lie algebra
Abstract: We propose a construction for character sheaves on loop Lie algebras, generalizing Lusztig’s construction in the case of Lie algebras. (joint work with Zhiwei Yun)
