有向图上的里奇曲率
The Ricci curvature on directed graphs
摘要：
本文基于Lin-Lu-Yau的定义，研究了有向图的里奇曲率.给出了里奇曲率的一些性质，包括有向正则图为Ricci平坦图的条件.此外，我们还计算了有向图的笛卡儿积的里奇曲率。
英文摘要：
In this paper, we consider the Ricci curvature of a directed graph, based on Lin-Lu-Yau's definition. We give some properties of the Ricci curvature, including conditions for a directed regular graph to be Ricci-flat. Moreover, we calculate the Ricci curvature of the cartesian product of directed graphs.
