Domination Value in and
arXiv:1109.5908
Abstract
A set is a \emph{dominating set} of a graph if every vertex of not in is adjacent to at least one vertex in . A \emph{minimum dominating set} of , also called a -set, is a dominating set of of minimum cardinality. For each vertex , we define the \emph{domination value} of to be the number of -sets to which belongs. In this paper, we find the total number of minimum dominating sets and characterize the domination values for and .
