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 xy=yx {xy=yx} . In this paper, the structure of the commuting conjugacy class graph of group G with the property that GZ(G) {\frac{G}{Z(G)}} is isomorphic to a Frobenius group of order pq or p2q {p^{2}q} , is determined.
期刊介绍:
The Georgian Mathematical Journal was founded by the Georgian National Academy of Sciences and A. Razmadze Mathematical Institute, and is jointly produced with De Gruyter. The concern of this international journal is the publication of research articles of best scientific standard in pure and applied mathematics. Special emphasis is put on the presentation of results obtained by Georgian mathematicians.
