Tight, not semi--fillable contact circle bundles
Paolo Lisca, Andras I. Stipsicz
Extending our earlier results, we prove that certain tight contact structures on circle bundles over surfaces are not symplectically semi--fillable, thus confirming a conjecture of…

An infinite family of tight, not semi-fillable contact three-manifolds
Paolo Lisca, Andras I Stipsicz
We prove that an infinite family of virtually overtwisted tight contact structures discovered by Honda on certain circle bundles over surfaces admit no symplectic semi-fillings. Th…
