Characterization of $α$ -excellent $2$ -trees

Magda Dettlaff, Michael A. Henning, Jerzy Topp

A graph is $α$ -excellent if every vertex of the graph is contained in some maximum independent set of the graph. In this paper, we present two characterizations of the $α$ -excellen…

On $α$ -excellent graphs

M. Dettlaff, M. A. Henning, J. Topp

A graph $G$ is $α$ -excellent if every vertex of $G$ is contained in some maximum independent set of $G$ . In this paper, we characterize $α$ -excellent bipartite graphs, $α$ -excellen…

Common domination perfect graphs

Magda Dettlaff, Michael A. Henning, Jerzy Topp

A dominating set in a graph $G$ is a set $S$ of vertices such that every vertex that does not belong to $S$ is adjacent to a vertex in $S$ . The domination number $γ (G)$ of $G$ is t…
