Abstract

Let G be non-trivial graph. A subset D of the vertex set V(G) of a graph G is called a dominating set of G if every vertex in V - D is adjacent to a vertex in D. The minimum cardinality of a dominating set is called the domination number and is denoted by γ(G). If V - D contains a dominating set S of G, then S is called an inverse dominating set with respect to D. In an inverse dominating set S, every pair of vertices u and v in S such that (deg u, deg v ) =1, then S is called relatively prime inverse dominating set. The minimum cardinality of a relatively prime inverse dominating set is called relatively prime inverse dominating number and is denoted by γrp1(G). In this paper we find relatively prime inverse dominating number of some graphs.
