A graph G is called (k, d)\*-choosable if, for every list assignment L satisfying [L(v)l = k for all v E V(G), there is an L-coloring of G such that each vertex of G has at most d neighbors colored with the same color as itself. In this note, we prove that every planar graph without 4-cycles and /-c
## 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
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 t
