本文利用图的伴随多项式的性质及其伴随分解的图论方法,讨论了h(P_m(r,n+1)^SG ) 型图的伴随多项式的因式分解,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 h(P_m(r,n+1)^SG ) - shape by the properties of adjoint polynomials and graphs method of adjoint faetorization. Furthermore, we prove that chromatically equivalence of their complement graphs under the distinct conditions.
