Abstract
Entropy convexity in Wasserstein space supplies a notion of Ricci curvature for discrete weighted graphs. This talk develops its local interpretation through infinitesimal entropy changes, then applies the framework to specific graph families. Sharper estimates for cycles and abelian Cayley graphs illustrate the resulting improvements.
