接触手柄分解

Contact handle decompositions

Burak Ozbagci

摘要:

我们审查Giroux的接触手柄和接触手柄附件的三维,并显示旁路附件由一对接触1和2手柄。作为一个应用,我们描述了无限多个两两非同位素过扭曲的3-球的显式接触柄分解。我们还给出了另一种证明,证明每个紧切触3-流形(封闭或具有凸边界)都允许切触柄分解,这最初是Giroux的结果。

英文摘要:

We review Giroux's contact handles and contact handle attachments in dimension three and show that a bypass attachment consists of a pair of contact 1 and 2-handles. As an application we describe explicit contact handle decompositions of infinitely many pairwise non-isotopic overtwisted 3-spheres. We also give an alternative proof of the fact that every compact contact 3-manifold (closed or with convex boundary) admits a contact handle decomposition, which is a result originally due to Giroux.
