所有维度中的非平凡接触映射类示例

Examples of non-trivial contact mapping classes in all dimensions

Patrick Massot, Klaus Niederkrüger

摘要:

我们给出的例子接触在每一个维度的身份是顺利的同位素,但不是接触同位素的身份。事实上,我们证明了更强的声明,他们甚至不是辛伪同位素的身份。我们也给出了例子对接触态同构是光滑共轭彼此,但不是由接触态同构。

英文摘要:

We give examples of contactomorphisms in every dimension that are smoothly isotopic to the identity but that are not contact isotopic to the identity. In fact, we prove the stronger statement that they are not even symplectically pseudo-isotopic to the identity. We also give examples of pairs of contactomorphisms which are smoothly conjugate to each other but not by contactomorphisms.
