Abstract

The union-closed sets conjecture states that if a finite set A of finite sets is union-closed and A ≠ {∅}, then there exists an element in ∪ A A A that belongs to at least half of the sets in A. We present three new formulations of the union-closed conjecture in terms of matrices, graphs, and hypergraphs.
