图的色多项式系数与图的特征关系

On the Relation between the Coefficient of its Color Palymonial and the Character of Graph

研究了连通图周长c(G)(c(G)≥3)与它的色多项式系数a2,a3,L,an的关系,得到一些有用结果,同时也刻画了一些特殊图与它的色多项式系数a2,a3,L,an的对应关系.

In the paper we study the relation between the circumference c（G） of the connected graph and the monomial coefficient of its color palymonial,and obtain some valuable result. At the same time, we also describe the relevant relation between some particular graph and the monomial coefficient of their color palymonial.
