A set S of vertices of a graph G = (V, E) is a dominating set if every vertex of V (G) \ S is adjacent to some vertex in S. The domination number γ (G) is the minimum cardinality of a dominating set of G. The domination subdivision number sd γ (G) is the minimum number of edges that must be subdivided in order to increase the domination number. Velammal(More)
