顺从极小动力系统的极小斜积的构造
Construction of minimal skew products of amenable minimal dynamical systems
摘要:
对于紧致可度量化空间$Z$上的群的顺从极小拓扑自由动力系统$α$和满足温和条件的紧致可度量化空间$Y$,构造了$α$在$Z\times Y$上的极小斜积扩张.这推广了Alberner和Weiss的一个结果。我们还研究了由此结果所产生的极小动力系统的交叉积的纯无限性。特别地,我们推广了Rørdam和Sierakowski的一个结果.
英文摘要:
For an amenable minimal topologically free dynamical system $α$ of a group on a compact metrizable space $Z$ and for a compact metrizable space $Y$ satisfying a mild condition, we construct a minimal skew product extension of $α$ on $Z\times Y$. This generalizes a result of Glasner and Weiss. We also study the pure infiniteness of the crossed products of minimal dynamical systems arising from this result. In particular, we give a generalization of a result of Rørdam and Sierakowski.
