A note on lower bounds estimates for the Neumann eigenvalues of manifolds with positive Ricci curvature

preprint2011arXivOpen access

Abstract

We study new heat kernel estimates for the Neumann heat kernel on a compact manifold with positive Ricci curvature and convex boundary. As a consequence, we obtain new lower bounds for the Neumann eigenvalues which are consistent with Weyl's asymptotics.
