WebChromatic Polynomials for Graphs. The chromatic polynomial of a graph G is the polynomial C G ( k) computed recursively using the theorem of Birkhoff and Lewis. The theorem of Birkhoff and Lewis states: c G ( k) = c G − e ( k) − c G / e ( k) where e is any edge from G, and. G − e is the graph obtained from G by removing edge e.
