$S$ -packing colorings of distance graphs $G (Z, {2, t})$

Boštjan Brešar, Jasmina Ferme, Karolína Kamenická

Given a graph $G$ and a non-decreasing sequence $S = (a_{1}, a_{2}, \dots)$ of positive integers, the mapping $f : V (G) \to {1, \dots, k}$ is an $S$ -packing $k$ -coloring of $G$ if…

Packing chromatic numbers of finite super subdivisions of graphs

Rachid Lemdani, Moncef Abbas, Jasmina Ferme

The \textit{packing chromatic number} of a graph $G$ , denoted by , is the smallest integer $k$ such that the vertex set of $G$ can be partitioned into sets $V_{i}$ , $i\in \…
