Total coloring of pseudo-outerplanar graphs

Xin Zhang, Guizhen Liu

A graph is pseudo-outerplanar if each of its blocks has an embedding in the plane so that the vertices lie on a fixed circle and the edges lie inside the disk of this circle with e…

Edge covering pseudo-outerplanar graphs with forests

Xin Zhang, Guizhen Liu, Jian-Liang Wu

A graph is called pseudo-outerplanar if each block has an embedding on the plane in such a way that the vertices lie on a fixed circle and the edges lie inside the disk of this cir…

(1,λ)-embedded graphs and the acyclic edge choosability

Xin Zhang, Guizhen Liu, Jian-Liang Wu

A (1,λ)-embedded graph is a graph that can be embedded on a surface with Euler characteristic λ so that each edge is crossed by at most one other edge. A graph G is called α-linear…

List version of (,1)-total labellings

Yong Yu, Guanghui Wang, Guizhen Liu

The (,1)-total number of a graph is the width of the smallest range of integers that suffices to label the vertices and the edges of such that no two adjacent…

List (d,1)-total labelling of graphs embedded in surfaces

Yong Yu, Xin Zhang, Guizhen Liu

The (d,1)-total labelling of graphs was introduced by Havet and Yu. In this paper, we consider the list version of (d,1)-total labelling of graphs. Let G be a graph embedded in a s…

k-forested choosability of graphs with bounded maximum average degree

Xin Zhang, Guizhen Liu, Jian-Liang Wu

A proper vertex coloring of a simple graph is -forested if the graph induced by the vertices of any two color classes is a forest with maximum degree less than . A graph is $…
