Some Mader-perfect graph classes

Hui Lei, Siyan Li, Xiaopan Lian +1

The dichromatic number of $D$ , denoted by $χ (D)$ , is the smallest integer $k$ such that $D$ admits an acyclic $k$ -coloring. We use $ma d e r_{χ} (F)$ to d…

Weak-odd chromatic index of special digraph classes

Ruijuan Gu, Hui Lei, Xiaopan Lian +1

Give a digraph $D = (V (D), A (D))$ , let $\partial_{D}^{+} (v) = {v w ∣ w \in N_{D}^{+} (v)}$ and $\partial_{D}^{-} (v) = {uv ∣ u \in N_{D}^{-} (v)}$ be semi-cuts of $v$ . A mapping $φ : A (D) \to [k]$ is call…

Some extremal results on the chromatic-stability index

Shenwei Huang, Sandi Klavžar, Hui Lei +2

The $χ$ -stability index $es_{χ} (G)$ of a graph $G$ is the minimum number of its edges whose removal results in a graph with the chromatic number smaller than that of $G$ . In th…
