An upper bound on the fractional chromatic number of triangle-free subcubic graphs

Chun-Hung Liu

An $(a : b)$ -coloring of a graph $G$ is a function $f$ which maps the vertices of $G$ into $b$ -element subsets of some set of size $a$ in such a way that $f (u)$ is disjoint from $f(v…

Linear colorings of subcubic graphs

Chun-Hung Liu, Gexin Yu

A linear coloring of a graph is a proper coloring of the vertices of the graph so that each pair of color classes induce a union of disjoint paths. In this paper, we prove that for…
