报告摘要:
Contact structures on 3-manifolds are given by a hyperplane distribution in the tangent bundle satisfying a condition called 'complete non-integrability'. Contact strucutres fall into one of two classes: tight or overtwisted. Ozsvath and Szabo introduced invariants of contact structures using Heegaard Floer homology. In this talk, I will survey some recent results about the tightness and contact invariants of contact 3-manifolds via contact surgery. The talk is based on joint work with Fan Ding and Zhongtao Wu.
