On Locally Conformally Flat Manifolds with Positive Pinched Ricci Curvature题目:On Locally Conformally Flat Manifolds with Positive Pinched Ricci Curvature报告人:程亮 副教授 (华中师范大学)地点:腾讯会议室时间: 2023年12月21日 8:00-8:50摘要: By using the Yamabe flow, we prove that if $(M^n,g)$, $n\geq3$, is an $n$-dimensional locally conformally flat complete Riemannian manifold satisfying $Rc\geq \epsilon Rg>0$, then $M^n$ must be compact. Our result shows that Ha...程亮 副教授 (华中师范大学)腾讯会议室2023年12月21日 8:00-8:50
