Description
In this talk we start with an introduction to Roe algebras and the coarse assembly map. Some difficulties appear when one is trying to define the groupoid equivariant analogue. We will share some techniques to formulate a framework to define groupoid equivariant Roe algebras and the coarse index map, and show that the coarse index map is compatible with the Baum-Connes assembly map for groupoids.
