摘要

Let H be a hypergraph. For a k-edge coloring c: E(H) --> {1,..., k} let f(H, c) be the number of components in the subhypergraph induced by the color class with the least number of components. Let f(k) (H) be the maximum possible value of f(H, c) ranging over all k-edge colorings of H. If H is the complete graph K-n then, trivially, f(1)(K-n) = f(2)(K-n) = 1. In this paper we prove that for ngreater than or equal to6,f(3)(K-n) = [n/6] + 1 and supply close upper and lower bounds for f(k)(K-n) in case kgreater than or equal to4. Several results concerning the value of f(k)(K-n(r)), where K-n(r) is the complete r-uniform hypergraph on n vertices, are also established. (C) 2004 Elsevier Inc. All rights reserved.
