Symplectic fillings of virtually overtwisted contact structures on lens spaces
Edoardo Fossati
Symplectic fillings of standard tight contact structures on lens spaces are understood and classified. The situation is different if one considers non-standard tight structures (i.…
Hypersurface singularities and virtually overtwisted contact structures
Edoardo Fossati
It is known that the lens space supports a virtually overtwisted contact structure arising as the boundary of the Milnor fiber of a complex hypersurface singularity. In t…
Topological constraints for Stein fillings of tight structures on lens spaces
Edoardo Fossati
In this article we give a sharp upper bound on the possible values of the Euler characteristic for a minimal symplectic filling of a tight contact structure on a lens space. This e…
Contact surgery on the Hopf link: classification of fillings
Edoardo Fossati
Let be the two-component Hopf link. After choosing a Legendrian representative of with respect to the standard tight contact structure on we perform cont…
