AbstractIn 2021, we introduced one type of the generalization of dominator coloring via packing coloring and distance domination. In this paper, we present a second type of such generalization, namely
distance dominator packing coloring of type II , defined as follows. A coloringc is ak-distance dominator packing coloring of type II ofG if it is ak -packing coloring ofG and for eachu ∈V (G ) there existsi ∈ {1, 2, 3, . . . ,k } such thatu c (u )-distance dominates each vertex from the color class of colori (i.e., the distance betweenu and all vertices from color class of colori is at mostc (u )). The smallest integerk such that there exists ak -distance dominator packing coloring ofG is thedistance dominator packing chromatic number of type II ofG , denoted by . In this paper, we provide some lower and upper bounds on the distance dominator packing chromatic number of type II, characterize connected graphsG with , and consider the relation between the packing coloring, distance dominator packing coloring of type I (introduced by Ferme and Mesarič Štesl in 2021) and distance dominator packing coloring of type II for a given graph.
