Infinitely many universally tight contact manifolds with trivial Ozsvath-Szabo contact invariants

arXiv:math/0510574 · doi:10.2140/gt.2006.10.335

Abstract

In this article we present infinitely many 3-manifolds admitting infinitely many universally tight contact structures each with trivial Ozsvath-Szabo contact invariants. By known properties of these invariants the contact structures constructed here are non weakly symplectically fillable.
