P-Curvature Condition and Eigenvalue Estimate on the Graph题目:P-Curvature Condition and Eigenvalue Estimate on the Graph报告人:王林峰 教授 (南通大学)地点:腾讯会议室时间:2023年12月21日 14:00-14:50摘要:Let G(V,E) be a connected finite graph. In this report we firstly consider the p-Bakry-Émery curvature ( curvature) condition on G. We show that the condition holds on G for any . We establish eigenvalue estimates for the p-Laplace operator ...王林峰 教授 (南通大学)腾讯会议室2023年12月21日 14:00-14:50

The Affine Toda System: Local Mass and Affine Weyl Group题目:The Affine Toda System: Local Mass and Affine Weyl Group报告人:杨文 教授 (澳门大学)地点:腾讯会议室时间:2023年12月21日 13:00-13:50摘要: The local mass is a fundamental quantized information that characterizes the blow-up solution to the Toda system and has a profound relationship with its underlying algebraic structure. In a recent work we have observed that the associated Weyl gro...杨文 教授 (澳门大学)腾讯会议室2023年12月21日 13:00-13:50

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
