我们开发了一些新的工具来研究最小变换群(流),并应用这些工具将最小流的分类理论扩展到比以前分类的更大的类别。我们开发的工具源自 Furstenberg、Ellis 和 Veech 在证明有关远端流和点远端流的结构定理时所使用的技术的简化和统一。这种简化很大程度上是通过使用 Glasner 在 2X 结构上的最新结果(其点由给定流的相空间 X 的闭合子集组成)实现的。
We develop some new tools for the study of minimal transformation groups (flows) and apply these tools to extend the classification theory of minimal flows to a larger class than has previously been classified. The tools we develop arise from a simplification and unification of the techniques used by Furstenberg, Ellis, and Veech in their proofs of structure theorems about distal and point distal flows. This simplification is made possible largely through the use of recent results of Glasner on the structure of 2X(whose points consist of closed subsets of the phase spaceXof a given flow).
