非同构群上的两类Cayley图

Two families of graphs that are Cayley on nonisomorphic groups

Joy Morris, Josip Smolcic

摘要:

许多作者研究了一个图何时可以表示为多个非同构群上的Cayley图的问题。迄今为止的工作集中在几个特殊的情况下:当群体是$p$ -群体;当群体有秩序$pq$ ;当凯莱图是正常的;或当群体都是阿贝尔。本文构造了两个无限图族,每个图族都是阿贝尔群和非阿贝尔群上的Cayley图.这些族包括了在其他结果中没有出现的这种图的最小的例子。

英文摘要:

A number of authors have studied the question of when a graph can be represented as a Cayley graph on more than one nonisomorphic group. The work to date has focussed on a few special situations: when the groups are $p$-groups; when the groups have order $pq$; when the Cayley graphs are normal; or when the groups are both abelian. In this paper, we construct two infinite families of graphs, each of which is Cayley on an abelian group and a nonabelian group. These families include the smallest examples of such graphs that had not appeared in other results.
