Tight contact structures on some small Seifert fibered 3--manifolds
Paolo Ghiggini, Paolo Lisca, Andras I. Stipsicz
We classify tight contact structures on the small Seifert fibered 3--manifold M(-1; r_1, r_2, r_3) with r_i in (0,1) and r_1, r_2 \geq 1/2. The result is obtained by combining conv…

Ozsvath-Szabo invariants and tight contact three-manifolds, III
Paolo Lisca, Andras I. Stipsicz
We characterize L-spaces which are Seifert fibered over the 2-sphere in terms of taut foliations, transverse foliations and transverse contact structures. We give a sufficient cond…

Notes on the contact Ozsvath--Szabo invariants
Paolo Lisca, Andras I. Stipsicz
We prove various results on contact structures obtained by contact surgery on a single Legendrian knot in the standard contact three--sphere. Our main tool are the contact Ozsvath-…
