Legendrian网格一号纽结及其微分代数的扩充

Legendrian grid number one knots and augmentations of their differential algebras

Joan E. Licata

摘要:

本文研究紧透镜空间中Legendrian纽结的微分分次代数(DGA)不变量。给定一个网格编号为一个结在L(p,q)的图,我们展示了如何构建一个特殊的拉格朗日图适合于计算DGA不变的勒让德结指定的图。然后,我们专门为L(p,p - 1),并表明,对于两个家庭的结,存在的DGA的扩增仅取决于p的值。

英文摘要:

In this article we study the differential graded algebra (DGA) invariant associated to Legendrian knots in tight lens spaces. Given a grid number one diagram for a knot in L(p, q), we show how to construct a special Lagrangian diagram suitable for computing the DGA invariant for the Legendrian knot specified by the diagram. We then specialize to L(p, p - 1) and show that for two families of knots, the existence of an augmentation of the DGA depends solely on the value of p.
