Colouring of generalized signed planar graphs

Ligang Jin, Tsai-Lien Wong, Xuding Zhu

Assume $G$ is a graph. We view $G$ as a symmetric digraph, in which each edge $uv$ of $G$ is replaced by a pair of opposite arcs $e = (u, v)$ and $e^{- 1} = (v, u)$ . Assume $S$ is an inve…

Total weight choosability for Halin graphs

Yu-Chang Liang, Tsai-Lien Wong, Xuding Zhu

A proper total weighting of a graph $G$ is a mapping $ϕ$ which assigns to each vertex and each edge of $G$ a real number as its weight so that for any edge $uv$ of $G$ , $\sum_{e \i…
