摘要

两个完全图通过添加一些边连接起来。得到的图称为粘接图。我们添加的边越多，它的里奇曲率就越大。计算粘接图上每条边的Ricci曲率，得到使粘接图具有正Ricci曲率的最小边数。

A CONSTRUCTION OF GRAPHS WITH POSITIVE RICCI CURVATURE

Two complete graphs are connected by adding some edges. The obtained graph is called the gluing graph. The more we add edges, the larger the Ricci curvature on it becomes. We calculate the Ricci curvature of each edge on the gluing graph and obtain the least number of edges that result in the gluing graph having positive Ricci curvature.
