The equivariant index is a refinement of the classical Fredholm index in the presence of a group action. On Riemannian manifolds, there are formulas for the equivariant index of Dirac operators. We...
Distributions of positive type arise naturally in quantum field theory as two-point distributions. Motivated by this application, one would like to perform various constructions with such...
In the first part of this talk, we will discuss some results on smoothing properties of the Ricci flow. In particular, we will consider the Ricci flow out of spaces with edge type conical...
