Two graphs are chromatically equivalent if they have the same chromatic polynomials.A graph is said to be chromatically unique if each graph which has same chromatic polynomial is isomorphic with it.Similarly,two graphs are adjointly equivalent if they have the same adjoint polynomials.A graph is said to be adjointly unique if each graph which has same adjoint polynomial is isomorphic with it.As we all know,two graphs are chromatically equivalent if their complement are adjointly equivalent;a graph is chrom...
