set in a graph Gis a minimal dominating set of G. The upper domination number of G, denoted by (G), is the maximum size of a minimal dominating set. Hence we have the following inequalities: Theorem ([6]) For every graph G, (G) i(G) (G) (G). Indeed, this is part of the canonical domination . Share your videos with friends, family, and the world.

The domination number is the minimum cardinality of a dominating set of. As introduced in, a subset is a 2 -dominating set if every vertex of has at least two neighbors in. The 2-domination number is the minimum cardinality of a 2-dominating set of. In a graph G = (V, E) if we think of each vertex s as the possible location for a guard capable of protecting each vertex in its closed neighborhood N[s], then “domination” requires every vertex to be xmilf.xyz, S ⊂ V(G) is a dominating set if ∪ s∈S N[s] = V(G).For total domination, each guard must, in turn, be protected, so we would want ∪ s∈S N(s) = V(G).

in domination is given in the book edited by Haynes et al. [5]. Various types of domination have been deﬁned and studied by several N(S) contains at least one vertex of N(S) − N(S −{u.
