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.

曲面上的三色无三角形图 VI。3-四边形的可着色性
我们给出了一个线性时间算法来确定固定表面四边形的 3 着色性(并找到 3 着色性,如果存在)。该算法还允许指定有限数量的顶点的着色。
