通过允许的横向手术实现紧密切触结构

Tight Contact Structures via Admissible Transverse Surgery

James Conway

摘要:

本文研究了在切触三维流形上的紧结和过扭结之间的关系。当接触结构$ξ_K$由纽结$K \subset M$支撑时,我们获得了当负手术导致具有非零Heegaard Floer接触类的切触结构时的表征。为此,我们利用镜像结$\overline{K} \subset -M$支持的切触结构$ξ_{\overline{K}}$的相关信息。我们得到了几个推论的存在紧密的切触结构,L-空间结外的$S^3$,非平面切触结构,和非平面勒让德结。

英文摘要:

We investigate the line between tight and overtwisted for surgeries on fibred transverse knots in contact 3-manifolds. When the contact structure $ξ_K$ is supported by the fibred knot $K \subset M$, we obtain a characterisation of when negative surgeries result in a contact structure with non-vanishing Heegaard Floer contact class. To do this, we leverage information about the contact structure $ξ_{\overline{K}}$ supported by the mirror knot $\overline{K} \subset -M$. We derive several corollaries about the existence of tight contact structures, L-space knots outside $S^3$, non-planar contact structures, and non-planar Legendrian knots.
