Abstract:

In 2002, Bollobas and Scott posed the following problem: for an integer k >= 2 and a graph G of m edges, what is the smallest f(k, m) such that V(G) can be partitioned into V-1,..., V-k in which e(V-i boolean OR V-j) <= f (k, m) for all 1 <= i not equal j <= k, where e(V-i boolean OR V-j) denotes the number of edges with both ends in V-i boolean OR V-j? In this paper, we solve this problem asymptotically by showing that f (k, m) <= m/(k - 1) + o(m). We also show that V(G) can be partitioned into V-1,..., V-k such that e(V-i boolean OR V-j) <= 4m/k(2) + 4 Delta/k + o(m) for 1 <= i not equal j <= k, where Delta denotes the maximum degree of G. This confirms a conjecture of Bollobas and Scott. (C) 2016 Wiley Periodicals, Inc.
