关于遍历保测变换的几类泛类

On some generic classes of ergodic measure preserving transformations

Eli Glasner, Jean-Paul Thouvenot, Benjamin Weiss

摘要:

我们肯定地回答了Ryzhikov的一个问题,即我们证明了在波兰群的保测变换中,作为一个相对弱的混合扩张是一个comeager性质。研究了几类相关的遍历变换及其相互关系。本文的第二部分证明了对于具有性质A的固定遍历T,T的一般扩张$\hat{T}$也具有性质A.这里A代表以下每个性质:(i)与T具有相同的熵,(ii)伯努利,(iii)K,(iv)松散伯努利。

英文摘要:

We answer positively a question of Ryzhikov, namely we show that being a relatively weakly mixing extension is a comeager property in the Polish group of measure preserving transformations. We study some related classes of ergodic transformations and their interrelations. In the second part of the paper we show that for a fixed ergodic T with property A, a generic extension $\hat{T}$ of T also has the property A. Here A stands for each of the following properties: (i) having the same entropy as T, (ii) Bernoulli, (iii) K, and (iv) loosely Bernoulli.
