Truncated degree DP-colourability of $K_{2, 4}$ -minor free graphs

On-Hei Solomon Lo, Cheng Wang, Huan Zhou +1

Assume $G$ is a graph and $k$ is a positive integer. Let $f$ from $V (G)$ to $N$ be defined as $f (v)$ is the minimum of $k$ and $d (v)$ . If $G$ is $f$ -DP-colourable (respectively, $…

Defective acyclic colorings of planar graphs

On-Hei Solomon Lo, Ben Seamone, Xuding Zhu

This paper studies two variants of defective acyclic coloring of planar graphs. For a graph $G$ and a coloring $φ$ of $G$ , a 2CC transversal is a subset $E^{'}$ of $E (G)$ that interse…
