Seminars in Mathematical Sciences

May 20 16:00 Richard van Dongen (University of Mons): Self-dual holography

In flat space, self-dual theories are powerful toy models for studying their parent theories. Here we develop an AdS/CFT framework for such self-dual theories and we discuss the holographic relation between chiral higher-spin gravity and Chern-Simons vector models. As an example, we discuss the relation between Yang-Mills and self-dual Yang-Mills in AdS. For mixed boundary conditions, explicit three- and four-point correlation functions in Yang-Mills are presented in several gauges, and we show how the self-dual limit emerges. The same correlators will be presented for the higher-spin extension of self-dual Yang-Mills.

Jun 11 13:00 Zhang Rongkai (Osaka): Rigidity of the Borell-Brascamp-Lieb inequality

Optimal transport theory has been a powerful tool in analysis on geometric spaces with curvature bounded since its introduction into geometric analysis. In this talk, I will first briefly introduce the application of the optimal transport theory on Riemannian manifolds and show an interpolation inequality. I will then focus on the recent work of mine, rigidity on curvature and measure of the Borell-Brascamp-Lieb inequality on weighted Riemannian manifolds satisfying the curvature dimension condition. I will also discuss the Brunn-Minkowski inequality and its rigidity, as well as a few open questions related.
