摘要

在本文中,我们给出了明确的条件,描述了因数为有限里程表的福尔纳一级群作用、因数为任意但指定里程表的群作用以及因数为未指定里程表的群作用。我们还给出了明确的条件,描述了与特定里程表共轭的福尔纳等级一动作,以及与某些里程表共轭的福尔纳等级一动作。这些条件基于生成作用的切割和堆叠程序,并概括了福尔曼、高、希尔、席尔瓦和韦斯给出的秩一 Z 作用的结果。

Finite odometer factors of rank one group actions
In this paper, we give explicit conditions characterizing the Følner rank one group actions that factor onto a finite odometer; those that factor onto an arbitrary, but specified odometer, and those that factor onto an unspecified odometer. We also give explicit conditions describing the Følner rank one actions that are conjugate to a specific odometer, and those that are conjugate to some odometer. These conditions are based on cutting and stacking procedures used to generate the action, and generalize results given by Foreman, Gao, Hill, Silva and Weiss for rank one Z-actions.
