本文研究了Floor-Auslander系统及其多重回归性。设(X,T)为Floor-Auslander系统,π:X→ Y为从(X,T)到里程表(Y,S)的因子映射.证明了存在Y的剩余子集Y 0,使得对于每个y∈ Y 0,π− 1(y)是一个单点,它是一个多重回归点;对于y∈ Y <$Y0,π− 1(y)中的每个点都不是一个2-多重回归点.
In this paper, we study the Floyd-Auslander system and its multiple recurrent properties. Let (X, T) be the Floyd-Auslander system, and let π: X→ Y be the factor map from (X, T) to an odometer (Y, S). We show that there exists a residual subset Y 0 of Y such that for each y∈ Y 0, π− 1 (y) is a singleton which is a multiple recurrent point, and for y∈ Y∖ Y 0, each point in π− 1 (y) is not a 2-multiple-recurrent point.
