Abstract
Let be a finite group. For a fixed element in and a given subgroup of , the relative -noncommuting graph of is a simple undirected graph whose vertex set is and two vertices and are adjacent if or and . We denote this graph by . In this paper, we obtain computing formulae for degree of any vertex in and characterize whether is a tree, star graph, lollipop or a complete graph together with some properties of involving isomorphism of graphs. We also present certain relations between the number of edges in and certain generalized commuting probabilities of which give some computing formulae for the number of edges in . Finally, we conclude this paper by deriving some bounds for the number of edges in .
