An index theorem for proper cocompact actions of Lie groupoids Tang, Xiang
Given a proper, cocompact action of a Lie groupoid, we define a higher index pairing between invariant elliptic differential operators and smooth groupoid cohomology classes. We will explain a cohomological index formula computing this pairing. This is joint work with Markus Pflaum, and Hessel Posthuma.
