摘要:设G是一个有限非交换群,ГG是G的一个交换图,这个交换图TG的顶点集为群G的所有元素,TG的两个不同顶点x和y是相连的当且仅当xy=yx.该文研究了交换图的一些性质,具体介绍了几个交换图同构的例子.
Let G be a finite non-abelian group. The commuting graph ГG of G with vertex set G and two different vertices x and y are adjacent if and only if xy =yx. In the following paper we inves- tigate some properties of the commuting graphs of some finite non-abelian groups and then we discuss some examples about the commuting graphs of finite non-abelian groups.
