An $\epsilon$-Regularity Theorem for Non-collapsed Ricci Flow

Differential Geometry 2025-10-24 v2

Abstract

In this article we prove an ϵ\epsilon-regularity theorem for non-collapsed Ricci flows, and use this to prove new estimates for singularity models of Fano K\"ahler-Ricci flows. In the course of our proof, we find a criterion for uniform convergence of solutions to the heat equation along a sequence of F\mathbb{F}-converging Ricci flows, and apply this to new parabolic regularizations of some natural geometric quantities.
