We conclude almost splitting and quantitative stratification theorems that have been established by Bamler for Ricci flow. As a byproduct, we obtain an almost constancy for a certain integral quantity concerning scalar curvature at an almost selfsimilar point, which is new even for Ricci flow.Ricci flowScalar curvatureWeak & singular flowsStability & uniqueness https://neckpinch.com/papers/2201.11361/arxiv:2201.11361Thu, 27 Jan 2022 00:00:00 GMTKeita Kunikawa, Yohei Sakurai — Bamler-Zhang have developed geometric analysis on Ricci flow with scalar curvature bound. The aim of this paper is to extend their work to various geometric flows. We generalize some of their results to super Ricci flow whose Muller quantity is non-negative, and obtain Gaussian heat kernel estimates.Ricci flowHeat kernelScalar curvatureWeak & singular flows
