A Gradient Estimate for Solutions of the Heat Equation II [PDF]

open access: yesCzechoslovak Mathematical Journal, 2001
summary:The author obtains an estimate for the spatial gradient of solutions of the heat equation, subject to a homogeneous Neumann boundary condition, in terms of the gradient of the initial data. The proof is accomplished via the maximum principle; the

A gradient estimate for all positive solutions of the conjugate heat equation under Ricci flow [PDF]

open access: yesJournal of Functional Analysis, 2008
We establish a point-wise gradient estimate for all positive solutions of the conjugate heat equation. This contrasts to Perelman's point-wise gradient estimate which works mainly for the fundamental solution rather than all solutions.
