Domination Parameters of a Graph and its Complement

Wyatt J. DesormeauxTeresa W. HaynesMichael A. Henning — 2018

Discussiones Mathematicae Graph Theory

A dominating set in a graph G is a set S of vertices such that every vertex in V (G) S is adjacent to at least one vertex in S, and the domination number of G is the minimum cardinality of a dominating set of G. Placing constraints on a dominating set yields different domination parameters, including total, connected, restrained, and clique domination numbers. In this paper, we study relationships among domination parameters of a graph and its complement.

A Note on Non-Dominating Set Partitions in Graphs

Wyatt J. DesormeauxTeresa W. HaynesMichael A. Henning — 2016

Discussiones Mathematicae Graph Theory

A set S of vertices of a graph G is a dominating set if every vertex not in S is adjacent to a vertex of S and is a total dominating set if every vertex of G is adjacent to a vertex of S. The cardinality of a minimum dominating (total dominating) set of G is called the domination (total domination) number. A set that does not dominate (totally dominate) G is called a non-dominating (non-total dominating) set of G. A partition of the vertices of G into non-dominating (non-total dominating) sets is...
