In the Fall of 2021, we will hold **online meetings** on
Zoom platform
(available every **Friday 1:00pm - 2:30pm**).

## Fall 2021

Oct. 23 | Yu Li (Stony Brook) | On the ancient solutions to the Ricci flow | (Huang) |

## 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.
