R覆盖Anosov流的纽结理论:闭轨道的同伦与合痕

Knot theory of R-covered Anosov flows: homotopy versus isotopy of closed orbits

Thomas Barthelmé, Sergio R. Fenley

摘要:

本文研究了紧致三维流形中R-覆盖Anosov流的周期轨道所实现的纽结。我们表明,如果两个轨道是自由同伦的,那么实际上他们是同位素。我们表明,电梯的周期轨道的普遍覆盖是unknotted。当流形是超环面的,我们推导出一些更精细的性质有关的存在性嵌入圆柱连接两个给定的同伦轨道。

英文摘要:

In this article, we study the knots realized by periodic orbits of R-covered Anosov flows in compact 3-manifolds. We show that if two orbits are freely homotopic then in fact they are isotopic. We show that lifts of periodic orbits to the universal cover are unknotted. When the manifold is atoroidal, we deduce some finer properties regarding the existence of embedded cylinders connecting two given homotopic orbits.
