Abstract:
Bollobas and Scott showed that the vertices of a graph of m edges can be partitioned into k sets such that each set contains at most m/k(2) o(m) edges. They conjectured that the vertices of an r-uniform hypergraph, where r > 3, of m edges may likewise be partitioned into k sets such that each set contains at most m/kr o(m) edges. In this paper, we prove the weaker statement that a partition into k sets can be found in which each set contains at most m/(k-1)(r)+r(1/2) +o(m) edges. Some partial results on this conjecture are also given. (C) 2016 Elsevier Inc. All rights reserved.
