论文摘要
在先前的工作中,作者为有向图引入了lin-lu-yau类型的RICCI曲率,并获得了引擎盖的直径比较。在本文中,我们研究了平等案例的刚性特性,并得出结论Cheng类型的最大直径定理。
In a previous work, the authors have introduced a Lin-Lu-Yau type Ricci curvature for directed graphs, and obtained a diameter comparison of Bonnet-Myers type. In this paper, we investigate rigidity properties for the equality case, and conclude a maximal diameter theorem of Cheng type.
