摘要
Let P(G, gimel) denote the chromatic polynomial of a graph G. Two graphs G and H are chromatically equivalent, written G similar to H, if P(G, gimel) = P(H, gimel). A graph G is chromatically unique, written x-unique, if for any graph H, G similar to H implies that G is isomorphic with H. In this paper we prove the chromatic uniqueness of a new family of 6-bridge graphs.
