| Abstract： | A graph is Ricci-flat, if the Ricci curvature vanishes on all edges. Here we use the definition of Ricci curvature on graphs given by Lin-Lu-Yau, which is a variation of coarse Ricci curvature of metric spaces given by Ollivier. We classify all connected, simple Ricci flat graphs with maximal degree at most 4. |
