Modified Ollivier's Ricci curvature on graphs and Ricci-flat graphs
- Yong Lin (Renmin University of China, Beijing)
Abstract
We modify the definition of Ricci curvature of Ollivier of Markov chains on graphs to study the properties of the Ricci curvature of general graphs, Cartesian product of graphs, random graphs. We also classify the Ricci-flat graphs with girth bigger than 5.
