摘 要: | 一个图G的完全亏格多项式表征了图G的亏格(可定向,不可定向)分布情况.本文推广了Yang和Liu提出的图类,得到了一类新的四正则图,并得出了此类四正则图的完全亏格分布.

Abstract: | The total genus polynomial for a graph G shows the genus (orientable, nonorientable) distribution of the graph G. In this paper, We obtain the total genus distributions for a class of 4-regular graphs which is a popularization of graphs posed by Yang and Liu (Acta Math Sinica, 2007,50(5): 1191 - 1200). |
