Ricci curvature on Riemannian manifolds has been well studied while there is no satisfied parallel notion for graphs or more general metric spaces. There are curvature notions defined on graphs by Ollivier, and on finitely generated groups by Bar-Natan - Duchin - Kropholler, which behaves like Ricci curvature in many senses. In this talk, I will explain the notions, some examples, some analog results , and some unanswered questions. No advanced background knowledge is needed. Speaker(s): Thang Nguyen (U Michigan)
