On gradient estimates for the heat kernel

Analysis of PDEs 2018-08-14 v3 Differential Geometry

Abstract

We study pointwise and LpL^p gradient estimates of the heat kernel, on manifolds that may have some amount of negative Ricci curvature, provided it is not too negative (in an integral sense) at infinity. We also prove uniform boundedness results on LpL^p spaces for the heat operator of the Hodge Laplacian on differential forms.
