Class I: Analytic Grothendieck Riemann Roch Theorem

In this talk, we will introduce an interesting index problem naturally associated to the Arveson-Douglas conjecture in functional analysis. This index problem is a  generalization of the classical Toeplitz index theorem, and connects to many different branches of Mathematics. In particular, it can be viewed as an analytic version of the Grothendieck Riemann Roch theorem. This is joint work with R. Douglas,M. Jabbari, and G. Yu.

Class II: Hochschild Homology of Proper Lie Groupoids

Hochschild homology provides the algebraic model for  differential forms. In this talk, we will report our recent study of Hochschild homology of proper Lie groupoids. This is joint work with M. Pflaum, and H. Posthuma.
