Abstract spectively). Note that d(G) is well-defined for every finite, undirected graph, while d t (G) is defined only for graphs without isolated vertices. Consider in G a vertex v of minimum valency #(G). Then a dominating set must contain v or a neighbour of v, thus it is obvious that d(G) 6 #(G) + 1. A total dominating set must contain a neighbour of v, thus d t (G) 6 #(G). We shall consider the case when a graph G is the union of two graphs G 1 , G 2 having exactly one common vertex a; this vertex a is a cut-vertex of G. The gra
