Filtering the Heegaard Floer contact invariant
Abstract
We define an invariant of contact structures in dimension three from Heegaard Floer homology. This invariant takes values in the set . It is zero for overtwisted contact structures, for Stein fillable contact structures, non-decreasing under Legendrian surgery, and computable from any supporting open book decomposition. As an application, we obstruct Stein fillability on contact 3-manifolds with non-vanishing Ozsv\'ath-Szab\'o contact class.

The contents of Section 5 are removed for future investigation. New application obstructing Stein fillability of contact 3-manifolds with non-vanishing Ozsvath-Szabo contact class is added as Section 5
