The Geometry and Topology seminar meets in room 901 of Van Vleck Hall on Fridays from 1:20pm - 2:10pm. For more information, contact Shaosai Huang.

In the fall of 2020, we will hold online meetings on Zoom platform (available every Friday 1:00pm - 2:30pm).

Fall Abstracts

Yu Li

Ancient solutions model the singularity formation of the Ricci flow.  In two and three dimensions, we currently have complete classifications for κ-noncollapsed ancient solutions, while the higher dimensional problem remains open. This talk will survey some recent developments of κ-noncollapsed ancient solutions with nonnegative curvature in higher dimensions.
