Tight contact structures on small Seifert fibrations
In this talk, I will briefly review the history of tight contact structures on small Seifert fibered spaces. I will introduce a new classification strategy for tight contact structures on Seifert fibered spaces. As an application, we classify tight structures on every surgery of every torus knot in the 3-sphere. As a consequence, we disprove a conjecture of Ghiggini and Van Horn-Morris regarding symplectic fillings of a family of Brieskorn spheres. This is joint work with Etnyre, Tosun, and Varvarezos.
