Gradient estimates for weighted harmonic function with Dirichlet boundary condition

Differential Geometry 2021-07-14 v2

Abstract

We prove a Yau's type gradient estimate for positive ff-harmonic functions with the Dirichlet boundary condition on smooth metric measure spaces with compact boundary when the infinite dimensional Bakry-Emery Ricci tensor and the weighted mean curvature are bounded below. As an application, we give a Liouville type result for bounded ff-harmonic functions with the Dirichlet boundary condition. Our results do not depend on any assumption on the potential function ff.
