The point-thicknesses of complete multipartite graphs

Wenzhong Liu, Wangkai Zhang

The point-thickness $θ^{'} (G)$ of a graph $G$ is the minimum number of subsets into which the vertex set $V (G)$ of $G$ is partitioned such that each subset induces a planar subgraph.…

Minimal quadrangulations of surfaces

Wenzhong Liu, M. N. Ellingham, Dong Ye

A quadrangular embedding of a graph in a surface $Σ$ , also known as a quadrangulation of $Σ$ , is a cellular embedding in which every face is bounded by a $4$ -cycle. A quadrangulati…

Quadrangular embeddings of complete graphs and the Even Map Color Theorem (with details)

Wenzhong Liu, Serge Lawrencenko, Beifang Chen +5

Hartsfield and Ringel constructed orientable quadrangular embeddings of the complete graph $K_{n}$ for $n \equiv 5 (mod 8)$ , and nonorientable ones for $n \geq 9$ and $n\equiv 1 \pmod…
