关于弱混合一致刚性遍历变换

On ergodic transformations that are both weakly mixing and uniformly rigid

Jennifer James, Thomas Koberda, Kathryn Lindsey, Cesar E. Silva, Peter Speh

摘要:

我们研究了一致刚性变换的一些性质,并分析了一致刚性和(可测)弱混合的相容性以及它们的一些渐近收敛性质.证明了在Cantor空间上不存在有限的保测、全遍历、一致刚性变换。我们简要地讨论了一般的群作用,并表明(可测)弱混合和均匀刚性可以共存于一个更一般的设置。

英文摘要:

We examine some of the properties of uniformly rigid transformations, and analyze the compatibility of uniform rigidity and (measurable) weak mixing along with some of their asymptotic convergence properties. We show that on Cantor space, there does not exist a finite measure-preserving, totally ergodic, uniformly rigid transformation. We briefly discuss general group actions and show that (measurable) weak mixing and uniform rigidity can coexist in a more general setting.
