Planar graphs without 5-cycles and intersecting triangles are $(1, 1, 0)$ -colorable

Runrun Liu, Xiangwen Li, Gexin Yu

A $(c_{1}, c_{2}, ..., c_{k})$ -coloring of $G$ is a mapping $φ : V (G) \mapsto {1, 2, ..., k}$ such that for every $i, 1 \leq i \leq k$ , $G [V_{i}]$ has maximum degree at most $c_{i}$ , where $G [V_{i}]$ d…
