The list r-hued coloring of trees and unicyclic graphs

Yu Miao, Fengxia Liu

Let $r$ be a positive integer and $G$ be a graph. The list $r$ -hued chromatic number of $G$ , denoted by $χ_{L, r} (G)$ , is the smallest integer $k$ , such that for each $k$ -list $L$ o…

Partitioning 3-edge-colored complete equi-bipartite graphs by monochromatic trees under a color degree condition

Xueliang Li, Fengxia Liu

The monochromatic tree partition number of an $r$ -edge-colored graph $G$ , denoted by $t_{r} (G)$ , is the minimum integer $k$ such that whenever the edges of $G$ are colored with $r$ c…
