报告题目：Quantitative maximal rigidities of Ricci curvature

报告人：戎小春教授（首都师范大学和美国罗格斯大学）

摘要：In Riemannian geometry, a maximal rigidity on an n-manifold M of Ricci curvature bounded below by (n − 1)H is a statement that a geometric or topological quantity of M is bounded above by that of an n-manifold of constant sectional curvature H, and “=” implies that M is isometric to an n-space form.

The Cheeger-Colding-Naber theory on Ricci limit space initiated in establishing a quantitative maximal volume rigidity. In this talk, we will survey some recent advances in Metric Riemannian geometry in establishing quantitative maximal rigidities, or in extending (quantitative) maximal rigidities to some singular metric spaces (Alexandrov spaces, RCD*-spaces).
