Scientific paper

In this article we provide an infinite family of weakly symplectically
fillable contact structures with trivial Ozsvath-Szabo contact invariants over
Z/2Z. As a consequence of this fact, we show how Heegaard-Floer theory can
distinguish between weakly and strongly fillable contact structures.
