Non-collapsing of Ricci shrinkers with bounded curvature
Conghan Dong, Assistant Research Professor, Department of Mathematics, Duke University,

In this talk, I will discuss a non-collapsing result for Ricci shrinkers. I will show that for any simply connected Ricci shrinker with finite second homotopy group, uniformly bounded curvature implies uniformly non-collapsing. The proof will be based on an analysis of collapsing structures. This is joint with Yu Li.
