Periodic point free homeomorphisms and irrational rotation factors
arXiv:1908.05746 · doi:10.1017/etds.2020.88
Abstract
We provide a complete characterization of periodic point free homeomorphisms of the -torus admitting irrational circle rotations as topological factors. Given a homeomorphism of the -torus without periodic points and exhibiting uniformly bounded rotational deviations with respect to a rational direction, we show that annularity and the geometry of its non-wandering set are the only possible obstructions for the existence of an irrational circle rotation as topological factor. Through a very precise study of the dynamics of the induced -centralized skew-product, we extend and generalize considerably previous results of T. Jäger [Inventiones Mathematicae, 176 (2009), n. 3, 601-616].
