Li-Yau Type Gradient Estimates and Harnack Inequalities by Stochastic Analysis
In this paper we use methods from Stochastic Analysis to establish
Li-Yau type estimates for positive solutions of the heat equation.
In particular, we want to emphasize that Stochastic Analysis provides natural tools to
derive local estimates in the sense that the gradient bound at given point depends only
on universal constants and the geometry of the Riemannian manifold locally about this point.
