Liouville Theorem for Harmonic Maps from Riemannian Manifold with Compact Boundary

Differential Geometry 2023-04-06 v1

Abstract

In this note we will provide a gradient estimate for harmonic maps from a complete noncompact Riemannian manifold with compact boundary (which we call "Kasue manifold") into a simply connected complete Riemannian manifold with non-positive sectional curvature. As a consequence, we can obtain a Liouville theorem. We will also show the nonexistence of positive solutions to some linear elliptic equation on Kasue manifold.
