Some remarks on gradient estimates for heat kernels
This paper is concerned with pointwise estimates for the gradient of the heat kernel Kt, t>0, of the Laplace operator on a Riemannian manifold M. Under standard assumptions on M, we show that ∇Kt satisfies Gaussian bounds if and only if it satisfies certain uniform estimates or estimates in Lp fo...
