Abstract

Let G be a finite non-abelian group and g be a fixed element of G. In 2014, Tolue et al. introduced the g-noncommuting graph of G (denoted by $\Gamma_G^g$) with vertex set G and two distinct vertices x and y join by an edge if $[x,y]\neq g$ and $g^{-1}$. In this paper, we consider an induced subgraph of $\Gamma_G^g$ with vertex set $G\ Z(G)$ which is denoted by $\Delta_G^g$. We state some properties of $\Delta_G^g$ G and prove that two groups with isomorphic g-noncommuting graphs have the same order.
