题目：Positively curved 6-manifolds with non-Abelian symmetry

报告人: 刘宇航（美国宾州大学）

Abstract: Closed Riemannian manifolds with positive sectional curvature

are a class of fundamental objects in Riemannian geometry. There are few

known examples of such manifolds, each of which possesses interesting

geometric properties. In this talk, I will review a few classical results in

positive curvature, including Bonnet-Myers theorem and Synge theorem.

Then I will move to the special case of dim 6, talking about the

classification problem of positively curved 6-manifolds with certain non-

Abelian symmetry conditions. This is ongoing research on my thesis topic.
