利用图的伴随多项式的性质及其伴随分解的图论方法,我们讨论了Hs(i,j)型图的伴随多项式的因式分解,进而证明了在不同条件下这类图的补图的色等价性.
This paper is devoted to discuss the factorization of adjoint polynomials of graphs of-shape by the properties of adjoint polynomials and graphs method of adjoint factorization,furthermore,chromatically equivalence of their complement graphs under the distinct conditions is proved.
