Chromatic Polynomials and Chromaticity of Graphs 作者: Teo, K. L. 出版社: World Scientific Pub Co Inc 页数: 定价: $装帧: Pap ISBN: 豆瓣评分. This problem led to the development of useful tools for graphs coloring as Chromatic polynomials and Chromatic number. The graph coloring problem has a huge . Let P(G,λ) be the chromatic polynomial of a graph G with n vertices, independence number α and clique number ω. We show that for every λ≥n,$\frac\Box Author: David Avis, Caterina De Simone, Paolo Nobili.

By induction, the statement is true for all graphs with n vertices and any number of edges. These properties do not characterize the chromatic polynomials amongst all the polynomials with . Theorem is a generalization of Stanley’s chromatic reciprocity theorem for weak chromatic polynomials of mixed graphs. Theorem Let G = (V;E;A) be an acyclic mixed graph and let .

Because the Chromatic Function of a null graph is a polynomial (P N n (k) = kn), we see that the Chromatic Function of Gis equal to the sum of a large number. The study of chromatic polynomials of graphs was initiated by Birkhoff [3] in and continued by Whitney [49], [50] in Inspired by the four-colour conjecture, Birkhoff and Lewis [4].
