Abstract:

In this paper, for $r\in \mathbb {N}$ with $r\geq 2$ we consider several stronger versions of $r$-sensitivity and measure-theoretical $r$-sensitivities by analyzing subsets of non-negative integers, for which the $r$-sensitivity occurs. We obtain an Auslander-Yorke type dichotomy theorem: a minimal topological dynamical system is either thickly $r$-sensitive or an almost $m$-to-one extension of its maximal equicontinuous factor for some $m\in \{1,\cdots , r-1\}$.
