摘要
运用图的分数染色讨论了一类6-正则循环图的顶点染色,得到了邻接矩阵的首行具有形式(01110…0111)的n阶循环图G点色数:X(G)={4,4|n5,其它.
In this article,we use the fractional chromatic number to discuss the vertex coloring about a kind of cyclic graph of regularity of degree 6. And according to these results we get thd point-chromatic number of the circular graphs G with order that the first row of their adjacent matrix is （01110…0111） ：X（G）={4,4ln,n≥12,5,others of n≥12.
