Mini-course: Lie Groupoid C*-algebras and Applications to Twisted Index Theory (4 Lectures)

Bai-ling Wang 王百灵  (Australian National University)

14:00-16:00, April 9-12, 2018   Science Building A1510

Abstract:

In this lecture series, I will give an elementary introduction to differential geometry of Lie groupoids, groupoids $C^\ast$-algebras, pseudo-differential calculus and index theory on Lie groupoids. As an application, I will discuss joint work with Paulo Carrillo Rouse on the geometric twisted $K$-homology groups and the geometric assembly maps for twisted Lie groupoids (twisted differentiable stacks).
