Abstract: I'll introduce the concept of combinatorial Calabi flow on surfaces. Long time existence results will be proved based on the estimation of discrete Laplacian. Since this flow is closely related to discrete Laplacians, I'll also talk about several type of discrete Laplacians on a triangulated surface.
