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.
