Title: Normalized discrete Ricci flow and community detection

Abstract:

We prove the existence and uniqueness of solution of normalized discrete  Ricci flow on graphs. We also use the discrete Ricci flow on the graph cut   problems. These are based on the joint works with Bai, Lai, Lu, Wang and   Yau.
