%0 Journal Article %T Normal 0-1 polytopes %A Huy Tai Ha %A Kuei-Nuan Lin %J Mathematics %D 2013 %I arXiv %X We study the question of when 0-1 polytopes are normal or, equivalently, having the integer decomposition property. In particular, we shall associate to each 0-1 polytope a labeled hypergraph, and examine the equality between its Ehrhart and polytopal rings via the combinatorial structures of the labeled hypergraph. %U http://arxiv.org/abs/1309.4807v3
