摘要:

研究了T^2上的动力系统,它是T^1上无理旋转的群扩张.给出了二阶系统扩张最小和最大等度连续因子为无理旋转的判别准则。计算了扩张的拓扑复杂性,并对Host-Kra-Maass提出的一个公开问题的后半部分给出了否定的回答.

英文摘要:

The dynamical system on T^2 which is a group extension over an irrational rotation on T^1 is investigated. The criterion when the extension is minimal, a system of order 2 and when the maximal equicontinuous factor is the irrational rotation is given. The topological complexity of the extension is computed, and a negative answer to the latter part of an open question raised by Host-Kra-Maass is obtained.
