Algebraic Index Theorems for Orbifolds

Algebraic index theory goes back to the work of Fedosov, Nest and Tsygan and is based on the idea to prove index theorems a la Atiyah-Singer by studying the noncommutative geometry of deformation quantizations. This approach to index theory will be explained in the talk and applied to obtain index theorems for orbifolds. The talk is about joint work with Posthuma and Tang.
