## dedicated to professor w. t. tutte on the occasion of his eightieth birtday It is known that the chromatic number of a graph G=(V, E) with V= [1, 2, ..., n] exceeds k iff the graph polynomial f G => ij # E, i<j (x i &x j ) lies in certain ideals. We describe a short proof of this result, using

A recursion exists among the coefficients of the color polynomials of some of the families of graphs considered in recent work of Balasubramanian and Ramaraj.' Such families of graphs have been called Fibonacci graphs. Application to king patterns of lattices is given. The method described here appl
## Abstract Graph bundles generalize the notion of covering graphs and products of graphs. Several results about the chromatic numbers of graph bundles based on the Cartesian product, the strong product and the tensor product are presented. © 1995 John Wiley & Sons, Inc.
We present algorithms for minimum G -coloring k-colorable graphs drawn from random and semi-random models. In both models, an adversary initially splits Ž . the vertices into k color classes V , . . . , V of sizes ⍀ n each. In the first model,
## Abstract In the set of graphs of order __n__ and chromatic number __k__ the following partial order relation is defined. One says that a graph __G__ is less than a graph __H__ if __c__~__i__~(__G__) ≤ __c__~__i__~(__H__) holds for every __i__, __k__ ≤ __i__ ≤ __n__ and at least one inequality is
