Spaces with Ricci curvature lower bounds, pt. 1

Abstract

Zoom Link

Ricci curvature lies between the sectional curvature and scalar curvature. It occurs naturally in Einstein equation, Ricci flow, optimal transport. We will review the basic tools (Bochner's formula, comparison inequalities) and survey many geometric inequalities (Neumann eigenvalue comparison, Brunn-Minkowski, Sobolev inequalities etc.), topological properties and examples in the smooth and nonsmooth settings.
