abstract: 'Giroux has described a correspondence between open book decompositions on a 3–manifold and contact structures. In this paper we use Heegaard Floer homology to give restrictions on contact structures which correspond to open book decompositions with planar pages, generalizing a recent result of Etnyre.'
