A set $D$ of vertices in $G$ is a disjunctive dominating set in $G$ if every vertex not in $D$ is adjacent to a vertex of $D$ or has at least two vertices in $D$ at distance $2$ fr…

Super domination in trees

Wei Zhuang

For $S \subseteq V (G)$ , we define $S ˉ = V (G) ∖ S$ . A set $S \subseteq V (G)$ is called a super dominating set if for every vertex $u \in S ˉ$ , there exists $v \in S$ such…
