Let $m\in\mathbb N$, and let a minimal $\mathbb Z$-system mean a minimal dynamical system with a continuous $\mathbb Z$-action. Its maximal equicontinuous factor is the maximal fac…

Let $(X,\varphi)$ be a minimal topological dynamical system, and let $(Y,\psi)$ be its maximal equicontinuous factor (MEF). For $m\in\mathbb{N}$, say that $(X,\varphi)$ is mean $m$…
