Description

In the 1980s, Alain Connes gave a conceptually appealing proof of the Atiyah-Singer index theorem using the tangent groupoid. Over time, the tangent groupoid was generalized to more complicated analytic settings. I will discuss the role played by groupoids in the resolution of the index problem for hypoelliptic differential operators on contact manifolds.
