Title：Parabolic Rectifiability of Singular Sets in Ricci Flow Limit Spaces
Abstract：In this talk, I will present recent results on the parabolic rectifiability of cylindrical singularities in Ricci flow limit spaces. As applications, I will discuss an L^1 curvature bound for four-dimensional closed Ricci flows and the resolution of Perelman's bounded diameter conjecture in dimension three. This is joint work with Hanbing Fang.
