Based on a global estimate of the heat kernel, some important inequalities such as Poincaré inequality and log-Sobolev inequality, furthermore a tight logarithm Sobolev inequality are presented on graphs, just under a positive curvature condition $CDE'(n,K)$ with some $K>0$. As consequences, we obtain exponential integrability of integrable Lipschitz functions and moment bounds at the same assumption on graphs.
Keywords: Log-Sobolev inequality, Laplacian
Mots-clés : $CDE'(n,K)$.
