讲座题目:On noncollapsed F-limit metric solitons
摘要: In this talk, we will introduce the metric solitons——they are natural generalizations of Ricci shrinkers, and they arise as singularity models when studying the Ricci flow with the tool of F-convergence. We will show that on the regular part of a noncollapsed F-limit metric soliton, many classical results concerning a Ricci shrinkers hold, such as, a potential function growth estimate, a volume growth estimate, a global Sobolev inequality, and a quadratic lower bound of the scalar curvature. This is a joint work with Pak-Yeung Chan and Zilu Ma.
