摘要
首先给出了不可分离面近正则 (除根面外 ,其它每个面的次均是常数k ,其中k≥ 3)外平面地图的色数、根面次和边数 3个参数的色计数函数所满足的方程 ,并给出了它的显式表达式 .然后 ,给出了可分离面近正则外平面地图的色数、根面次和边数
In this paper, firstly, we have given the chromatic enumerating equation of nonseparable face_near_regular outerplanar maps(except root_face, valency of others is constant k, and k≥3) with three parameters:chromatic number, valency of root_face and number of edges; and we have presented explicit formula. Then, we have presented the chromatic enumerating equation of separable face_near_regular outerplanar maps with three parameters: chromatic number, valency of root_face and number of edges.
