ABSTRACT

We extend the concept of singular Ricci flow by Kleiner and Lott from 3d compact manifolds to 3d complete manifolds with possibly unbounded curvature. As an application of the generalized singular Ricci flow, we show that for any 3d complete Riemannian manifold with non-negative Ricci curvature, there exists a smooth Ricci flow starting from it.

BRIEF BIO

Yi Lai is currently a Ph.D. candidate in the math department at UC Berkeley. Her adviser is Professor Richard Bamler. Her research interests lie in differential geometry, particularly in geometric analysis and Ricci flow.
