Title
Graph r-hued colorings-A survey
Abstract
A (k, r)-coloring of a graph G is a proper k-vertex coloring of G such that the neighbors of each vertex of degree d will receive at least min{d, r} different colors. The r-hued chromatic number, denoted by chi(r) (G), is the smallest integer k for which a graph G has a (k, r)-coloring. This article is intended to survey the recent developments on the studies related to this r-hued colorings. Emphases are on the r-hued colorings of planar graphs, graph families with forbidden minors, and sparse graphs, as well as on the comparison between the r-hued chromatic number and the chromatic number of a graph, and the sensitivity studies of the r-hued chromatic number. It also surveys other related results on r-hued colorings and list r-hued colorings. (C) 2022 Elsevier B.V. All rights reserved.
