Chromaticity of a family of K 4-homeomorph with Girth 9
For a graph G, let P(G,λ) denote the chromatic polynomial of G. Two graphs G and H are chromatically equivalent (or simply χ-equivalent), denoted by G ∼ H, if P(G,λ) = P(H,λ). A graph G is chromatically unique (or simply χ-unique) if for any graph H such as H ∼ G, we have H ≅ G, i.e, H is isomorphic...
