On -packing total colorings

Jasmina Ferme, Jaka Hedžet, Petra Melicharova +1

In this paper, we generalize the concept of packing total coloring by introducing a new concept called the -packing total coloring. For a graph and a non-decreasing sequence…

On packing total coloring

Jasmina Ferme, Daša Mesarič Štesl

In this paper, we introduce a new concept in graph coloring, namely the \textit{packing total coloring}, which extends the idea of packing coloring to both the vertices and the edg…

Packing chromatic numbers of finite super subdivisions of graphs

Rachid Lemdani, Moncef Abbas, Jasmina Ferme

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