AbstractDetermining the chromatic number of a graph is a difficult but important problem. Hence, it is not surprising that a variety of questions in Graph Theory concern the search for meaningful upper bounds for the chromatic number of certain families of graphs. One type of graph family that received considerable attention is that of H-free graphs, that is, the family of graphs G which do not...

Recent studies have revealed that, along the $\mathbb{Z}_p$-ex...
