摘要

我们给出了一种线性时间算法来确定一个固定曲面的四边形的可3色性(并找到一个3色，如果它存在的话)。该算法还允许为有限数量的顶点指定颜色。

Three-coloring triangle-free graphs on surfaces VI. 3-colorability of quadrangulations

We give a linear-time algorithm to decide 3-colorability (and find a 3-coloring, if it exists) of quadrangulations of a fixed surface. The algorithm also allows to prescribe the coloring for a bounded number of vertices.
