关于Anosov流和丛与纤维化Anosov流的自轨道等价性的注记

A note on self orbit equivalences of Anosov flows and bundles with fiberwise Anosov flows

Thomas Barthelmé, Andrey Gogolev

摘要:

我们表明,一个自轨道等价的传递Anosov流的$3$ -流形是同伦的身份要么保持每一个轨道或Anosov流是$\mathbb{R}$ -覆盖和轨道等价必须是一个特定的类型。这一结果表明,当纤维是$3$维时,可以消除Farrell和Gogolev关于支持纤维化Anosov流的丛的拓扑刚性的结果中的一个相对不自然的假设.

英文摘要:

We show that a self orbit equivalence of a transitive Anosov flow on a $3$-manifold which is homotopic to identity has to either preserve every orbit or the Anosov flow is $\mathbb{R}$-covered and the orbit equivalence has to be of a specific type. This result shows that one can remove a relatively unnatural assumption in a result of Farrell and Gogolev about the topological rigidity of bundles supporting a fiberwise Anosov flow when the fiber is $3$-dimensional.
