北航数学论坛学术报告 --微分几何讨论班(2024春第1讲)题目:On Finsler gradient Ricci solitons报告人:莫小欢 教授(北京大学)时间:2024年4月17日 10:00-10:50地点:沙河主E404摘要:In this lecture we discuss a class of Finsler measure space whose weighted Ricci curvature satisfies ${\bf Ric}_{\infty}=cF^{2}$. This class contains all gradient Ricci solitons and Finsler Gaussian solitons. Thus Finsler...

北航数学论坛学术报告Searching for hyperbolic periodic orbit by minimizing the action程崇庆(南京师范大学)报告时间:10:00-11:30,2024-04-08(星期一)报告地点: 沙河E-404内容简介:It was discovered by Poincare that minimal closed geodesic on surface is hyperbolic and Birkhoff thought it was also true for Riemannian manifold with higher dimensions. Unfortunately, Birkhoff's conjecture is wrong....
