演講摘要: 

A discrete surface is a simplicial complex which is locally isometric to $R^2$ or upper half plane, and we can define Gaussian curvature and circle packing metric on it, then we’ll explain the discrete Gauss-Bonnet theorem. Also, we can compute the relation between length of simplices and the metric and define Ricci flow, then I’ll prove the convergence of the discrete Ricci flow.
