By introducing the Ricci curvature lower bound on graphs, we prove the following result on graphs with non-negative Ricci curvature: The volume doubling and Poincare inequality, discrete-time heat kernel Gaussian estimate, parabolic Harnack inequality. These are the similar results on Riemannian manifold with non-negative Ricci curvature.
