Variable degeneracy of graphs with restricted structures

Qianqian Wang, Tao Wang, Xiaojing Yang

Bernshteyn and Lee defined a new notion, weak degeneracy, which is slightly weaker than the ordinary degeneracy. It is proved that strictly $f$ -degenerate transversal is a common g…

Planar graphs without normally adjacent short cycles

Fangyao Lu, Mengjiao Rao, Qianqian Wang +1

Let $G$ be the class of plane graphs without triangles normally adjacent to $8^{-}$ -cycles, without $4$ -cycles normally adjacent to $6^{-}$ -cycles, and without normally a…

Cover and variable degeneracy

Fangyao Lu, Qianqian Wang, Tao Wang

Let $f$ be a nonnegative integer valued function on the vertex set of a graph. A graph is \textbf{strictly $f$ -degenerate} if each nonempty subgraph $Γ$ has a vertex $v$ such that…
