Remarks on Li-Yau inequality on graphs

Differential Geometry 2013-11-15 v1 Combinatorics

Abstract

In this paper, we study Li-Yau gradient estimates for the solutions uu to the heat equation tu=Δu\partial_tu=\Delta u on graphs under the curvature condition CD(n,K)CD(n,-K) introduced by Bauer et al. in \cite{BHLLMY}. As applications, we derive Harnack inequalities and heat kernel estimates on graphs. Also we present a type of Hamilton gradient estimates.
