Positive Scalar Curvature and An Equivariant Higher Index Theory,   Lin Shan,   University of Muenster,  Wed, 1 July, 2009,   2:00 p.m. C-236


In this talk, I will talk about an equivariant higher index theory on complete Riemannian manifolds with a proper and isometric group action. This is a generalisation of Atiyah-Singer Index theory on compact manifolds. Also I will give one of its applications on the non-existence of positive scalar curvature on certain manifolds.
