On the existence of tight contact structures on Seifert fibered 3-manifolds

arXiv:0709.0737 · doi:10.1215/00127094-2009-024

Abstract

We determine the closed, oriented Seifert fibered 3-manifolds which carry positive tight contact structures. Our main tool is a new non-vanishing criterion for the contact Ozsvath-Szabo invariant.
