Abstract :
A subset S of vertices of a graph G is a dominating set of G if every vertex inV(G)−S has a neighbor in S. The domination number γ(G) of G is the minimum cardinality of a dominating set of G. In this paper, we obtain new (probabilistic)upper bounds for the domination number of a graph, and improve previous bounds given by Arnautov (1974), Payan (1975), and Caro and Roditty (1985) for any graph, and Harant, Pruchnewski and Voigt (1999) for regular graphs
