摘要
通过研究Γ_(r(2k+p)+1)^(ψ*G(i,j))类图簇的伴随多项式的因式分解,证明了这类图簇的补图的色等价图的结构性质和非色唯一性.
By studying the factorization of adjoint polynomials of a kind of Γ（r（2k＋p）＋1）^ψ＊G（i,j） - class graphs, We prove In this paper that structure characteristics of the chromatically equivalent graphs and chromatically non-uniqueness of their complement graphs.
