拓扑平凡勒让德结

Topologically Trivial Legendrian Knots

Y. Eliashberg, M. Fraser

摘要:

本文研究了紧切触三维流形和过扭切触三维流形中的拓扑平凡勒让德纽结。第一部分详细阐述了紧切触三维流形中拓扑平凡的勒让德纽结(即嵌入2-圆盘的勒让德纽结)的分类证明。这一部分基本上是10多年前写的,但只有一个简短的版本,没有详细的证明,发表(在CRM Proc. Lecture Notes,Vol. 15,1998)。该论文还简要讨论了过扭曲的情况。本文的最后一部分对过扭切触流形中的勒让德纽结进行了更系统的讨论,特别是对过扭切触S ^[3]中拓扑平凡的勒让德纽结进行了粗略的分类(即分类到整体切触同构)。

英文摘要:

The paper deals with topologically trivial Legendrian knots in tight and overtwisted contact 3-manifolds. The first part contains a thorough exposition of the proof of the classification of topologically trivial Legendrian knots (i.e. Legendrian knots bounding embedded 2-disks) in tight contact 3-manifolds. This part was essentially written more than 10 years ago, but only a short version, without the detailed proofs, was published (in CRM Proc. Lecture Notes, Vol. 15, 1998). That paper also briefly discussed the overtwisted case. The final part of the present paper contains a more systematic discussion of Legendrian knots in overtwisted contact manifolds, and in particular, gives the coarse classification (i.e. classification up to a global contactomorphism) of topologically trivial Legendrian knots in overtwisted contact S^3.
