✦ Synopsis
Recently, R6dl and Rucifiski [5,6] proved the following threshold result about Ramsey properties of random graphs. Let K(n, p) be the binomial random graph obtained from the complete graph K(n) by independent deletion of each edge with probability 1 -p. We write F ~ (G)r if for every r-coloring of the edges of F there is a monochromatic copy of G.

A graph is (rn, k)-colorable if its vertices can be colored with rn colors in such a way that each vertex is adjacent to at most k vertices of the same color as itself. In a recent paper Cowen. Cowen, and Woodall proved that, for each compact surface S, there exists an integer k = k(S) such that eve
## 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
In this article we discuss the current results on the list chromatic conjecture and prove that if G is a triangle free graph with maximum degree A then xi(G) 5 9A/5. If the term "a classic" can be used about a mathematical problem less than 10 years old, then surely the following question by Jeff D
## Abstract We study a concept of group coloring introduced by Jaeger et al. We show that the group chromatic number of a graph with minimum degree δ is greater than δ/(2, ln δ) and we answer several open questions on the group chromatic number of planar graphs: a construction of a bipartite planar
