Prekopa-Leindler inquality and the sharp Sobolev inequality

Daesung Kim   [email] (UIUC)

Abstract: Abstract: Prekopa-Leindler inequality is a functional version of Brunn-Minkowski inequality, and has a close relation to many interesting inequalities. We discuss the proof of Prekopa-Leindler inequality using optimal transport technique. As an application, we derive the sharp Sobolev inequality.

Introduction to the Stolz-Teichner Program

Connor Grady (UIUC Math)

Abstract: The Stolz-Teichner program is a far-reaching research program that aims to connect QFT to the cohomology of manifolds. Importantly for homotopy theorists, it is expected to provide a cochain model for TMF. In this talk I will sketch some of the broad strokes of the program and describe some of the partial results currently known.

Equivariant de Rham Cohomology and the Localization Theorem

Connor Grady (UIUC)

Abstract: In this talk I will discuss (Borel) equivariant cohomology, which is a cohomology theory for spaces equipped with a group action. I will then focus in on smooth manifolds and discuss two models constructed by Weil and Cartan, which are the analogs of de Rham cohomology in the equivariant setting. Finally, I will discuss the equivariant localization theorem and an application of this theorem to quantum field theory.
