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…

New inequalities involving the Geometric-Arithmetic index

J. M. Rodriguez, J. A. Rodriguez-Velazquez, J. M. Sigarreta

Let $G = (V, E)$ be a simple connected graph and $d_{i}$ be the degree of its $i$ th vertex. In a recent paper [J. Math. Chem. 46 (2009) 1369-1376] the first geometric-arithmetic index o…

The $k$ -metric dimension of the lexicographic product of graphs

A. Estrada-Moreno, I. G. Yero, J. A. Rodríguez-Velázquez

Given a simple and connected graph $G = (V, E)$ , and a positive integer $k$ , a set $S \subseteq V$ is said to be a $k$ -metric generator for $G$ , if for any pair of different vertices $…
