In this paper, we will present some characterizations for the upper bound of the Bakry-Emery curvature on a Riemannian manifold by using functional inequalities on path space. Moreover, some characterizations for general lower and upper bounds of Ricci curvature are also given, which extends the recent results derived by Naber \cite{N} and Wang-Wu\cite{WW}.
An upper bound on the number of self-avoiding polygons via joining
Ollivier curvature of random geometric graphs converges to Ricci curvature of their Riemannian manifolds
An improved upper bound for critical value of the contact process on $\mathbb{Z}^d$ with $d\geq 3$
