Abstract
WeprovethatSteinsurfaceswithboundarycoincideuptoorien- tation preserving diffeomorphisms with simple branched coverings of B4 whose branch set is a positive braided surface. As a consequence, we have that a smooth oriented 3-manifold is Stein fillable iff it has a positive open- book decomposition.
