This is a student reading seminar on the convergence of Ricci flows with bounded scalar curvature and entropy (co-organized with Jean-Francois Arbour). We will be reading the recent paper of Richard Bamler, Convergence of Ricci Flows with bounded scalar curvature. If interest prevails, we may also be consult the recent papers of Xiuxiong Chen and Bing Wang, Spaces of Ricci flows (I), (II).

The seminar will begin with some introductory talks on Perelman’s first paper (who L-geometry and induction of scale are motivations for Bamler’s techniques).

**Time and location:** Wednesday 17:00-18:30. Unless otherwise noted, we will meet at NYU Courant Institute Room 905.
