AI总结:

本文基于Lin-Lu-Yau公式计算了二面体群、广义四元数群和循环群在特定小生成集下Cayley图所有边的Ollivier Ricci曲率,给出了完整曲率结果。

摘要:

Lin、Lu和Yau提出了简单无向图中边的Ricci曲率公式[2]。利用他们的公式,我们计算了二面体群、广义四元数群和循环群的Cayley图的Ricci曲率,其中所选取的生成集的基数小于或等于四。对于二面体群和广义四元数群,我们得到了其Cayley图所有边的Ricci曲率,所用生成集由四个元素组成,即定义每个群的两个生成元及其逆元。对于循环群(Z/nZ, +),我们得到了由S_{1, k} = {+1, -1, +k, -k}生成的Cayley图的边的Ricci曲率。

英文摘要:

Lin, Lu, and Yau formulated the Ricci curvature of edges in simple undirected graphs[2]. Using their formulations, we calculate the Ricci curvatures of Cayley graphs for the dihedral groups, the general quaternion groups, and cyclic groups with some generating sets that are chosen so that their cardinal numbers are less than or equal to four. For the dihedral group and the general quaternion group, we obtained the Ricci curvatures of all edges of the Cayley graph with generator sets consisting of the four elements that are the two generators defining each group and their inverses elements.For the cyclic group (Z/nZ, +), we have the Ricci curvatures of edges of the Cayley graph generating by S_{1, k} = {+1, -1, +k, -k}.
