题目：Four-dimensional Ricci solitons with (half) nonnegative isotropic curvature

报告人：Professor Huai-Dong Cao (Lehigh University)

摘要：Ricci solitons, introduced by R. Hamilton in the mid-80s, are self-similar solutions to the Ricci flow and natural extensions of Einstein manifolds. In this talk, I will first discuss the significant role Ricci solitons play in understanding singularity formation in the Ricci flow and then present some recent progress on the classification of 4-dimensional gradient Ricci solitons with nonnegative, or half nonnegative, isotropic curvature. This is based on joint work with Junming Xie..
