Abstract

Abstract Let G be a finite non-abelian group. The commuting conjugacy class graph Γ ( G ) {\Gamma(G)} is defined as a graph whose vertices are non-central conjugacy classes of G and two distinct vertices X and Y in Γ ( G ) {\Gamma(G)} are connected by an edge if there exist elements x X {x\in X} and y Y {y\in Y} such that x y = y x {xy=yx} . In this paper, the structure of the commuting conjugacy class graph of group G with the property that G Z ( G ) {\frac{G}{Z(G)}} is isomorphic to a Frobenius group of order pq or p 2 q {p^{2}q} , is determined.
具有给定性质的有限群的交换共轭类图
设G是一个有限非阿贝尔群。交换共轭类图Γ (G) {\Gamma (G)}定义为这样一个图,其顶点是G的非中心共轭类,并且Γ (G) {\Gamma (G)中的两个不同的顶点X和Y}被一条边连接,如果存在元素X∈X X{\in X}和Y∈Y Y{\in Y,}使得X∈Y = Y∈X{ xy=yx}。本文确定了群G的交换共轭类图的结构,该图具有G Z∑(G){\frac{G}{Z(G)}}同构于pq阶或p 2∑q {p^{2q}阶的Frobenius群的性质。}
