Title
Some corollaries of a theorem of Whitney on the chromatic polynomial
Abstract
Let F denote the family of simple undirected graphs on v vertices having e edges, P ( G ; λ ) be the chromatic polynomial of a graph G . For the given integers v , e , λ , let f ( v , e , λ )= max\s{ P ( G;λ ): G ∈ F \s}. In this paper we determine some lower and upper bounds for f ( v , e , λ ) provided that λ is sufficiently large. In some cases f ( v , e , λ ) is found and all graphs G for which P ( G ; λ ) = f ( v , e , λ ) are described. Connections between these problems and some other questions from the extremal graph theory are analysed using Whitney's characterization of the coefficients of P ( G ; λ ) in terms of the number of ‘broken circuits’ in G .
