实心圆环面上紧切触结构的分类

Classification of tight contact structures on a solid torus

Zhenkun Li, Jessica J. Zhang

摘要:

对给定三维流形上的非同位素紧切触结构进行分类是切触几何中的一个基本问题。如果流形有边界,我们还需要指定边界上的分割集。本文给出了一个闭公式,给出了在任意给定的分割集上,非同位素紧切触结构的个数,从而完全回答了实心环面的分类问题。以前,只有少数特殊情况下,已知由于工作的本田。

英文摘要:

It is a basic question in contact geometry to classify all non-isotopic tight contact structures on a given 3-manifold. If the manifold has a boundary, we need also specify the dividing set on the boundary. In this paper, we answer the classification question completely for the case of a solid torus by writing down a closed formula for the number of non-isotopic tight contact structures with any given dividing set on the boundary of the solid torus. Previously, only a few special cases were known due to work by Honda.
