一个色多项式公式的改进及其讨论

A Improvement of Chormatic Polynomiai's formula and further Disscussion

文章通过对一个色多项式公式进行改进及讨论,得到一类组合恒等式和一个判断多项式不是色多项式的充分条件.

According to a chormatic polynomial＇s formula, we get several combinatorial identities and a sufficient condition which judges that a polynomical be not chormatic polynomial.
