The chromatically equivalence theorem of three kinds of combinatorial graphs

GONG Le-tian,ZHANG Bing-ru(Department of Mathematics,Qinghai Normal University,Xining 810008,Qinghai,China)  
Aim The chromatically equivalence of graphs was investigated.Methods The chromatically equivalence of graphs was analyzed by using factorization of adjoint polynomials of graphs.Results The factorizations and chromatically equivalent graphs were obtained from the combinatorial graphs consisting of Star Sn+1 and some isolated vertices.Conclusion The chromatically equivalence of graphs was obtained by researching into the adjoint factorizations of their complements.
