Let P(G,y) denote the chromatic polynomial of a graph G expressed in the variable y. A graph G is chromatically unique if P(G,y) = P(H,y) implies that H is isomorphic to G. It is proven that complements of partial matching forest are chromatically unique. An infinite family of counterexamples to the...
