On the $2$ -packing differential of a graph

A. Cabrera Martinez, M. L. Puertas, J. A. Rodriguez-Velazquez

Let $G$ be a graph of order $n (G)$ and vertex set $V (G)$ . Given a set $S \subseteq V (G)$ , we define the external neighbourhood of $S$ as the set $N_{e} (S)$ of all vertices in $V(G)\se…

From the strong differential to Italian domination in graphs

A. Cabrera Martinez, J. A. Rodriguez-Velazquez

Given a graph $G$ and a subset of vertices $D \subseteq V (G)$ , the external neighbourhood of $D$ is defined as $N_{e} (D) = {u \in V (G) ∖ D : N (u) \cap D \neq = \emptyset}$ , where…
