Abstract | Let G be a weighted hypergraph with edges of size i for i = 1, 2. Let wi denote the total weight of edges of size i and a be the maximum weight of an edge of size 1. We study the following partitioning problem of Bollobas and Scott: Does there exist a bipartition such that each class meets edges of total weight at least \ ? We provide an optimal bound for balanced bipartition of weighted hypergraphs, partially establishing this conjecture. For dense graphs, we also give a result for partitions into more than two classes. In particular, it is shown that any graph G with m edges has a partition V-1,...,V (k) such that each vertex set meets at least edges, which answers a related question of Bollobas and Scott. |
