Polynomial orbits in totally minimal systems

Jiahao Qiu

Inspired by the recent work of Glasner, Huang, Shao, Weiss and Ye, we prove that the maximal $\infty$ -step pro-nilfactor $X_{\infty}$ of a minimal system $(X, T)$ is the topological c…

Pro-nilfactors of the space of arithmetic progressions in topological dynamical systems

Zhengxing Lian, Jiahao Qiu

For a topological dynamical system $(X, T)$ , $l \in N$ and $x \in X$ , let $N_{l} (X)$ and $L_{x}^{l} (X)$ be the orbit closures of the diagonal point $(x, x, \dots, x)$ ( $l$ times) un…

A note on mean equicontinuity

Jiahao Qiu, Jianjie Zhao

In this note, it is shown that several results concerning mean equicontinuity proved before for minimal systems are actually held for general topological dynamical systems. Particu…
