报告摘要: We show that every graph with non-negative Ollivier Ricci curvature has at most two ends. In case of equality, the graph is quasi isometric to the line. The proofs can be seen as a first step in developing a concept of discrete minimal surfaces and discrete mean curvature. The talk is based on a joint work with Bobo Hua.
