Is the Union-closed sets conjecture the best possible?
Published online by Cambridge University Press: 09 April 2009
Abstract
A slightly strengthened version of the union-closed sets conjecture is proposed. It is shown that this version holds for a minimum set size of one or two and an examination of a boundary function shows that it holds for collections containing up to 19 sets. Some related conjectures are outlined.
