定义了秩1变换的标准有界性概念,并利用它刻画了具有平凡中心化子的有界秩1变换类。我们还明确地刻画了具有有界切割参数的全遍历秩1变换。再加上最近的结果Ryzhikov,我们的结果提供了一个简单的程序来确定,纯粹的切割和间隔参数的变换,是否有界秩-1变换有最小的自连接的所有订单。
We define the notion of canonical boundedness among rank-1 transformations and use it to characterize the class of bounded rank-1 transformations with trivial centralizer. We also explicitly characterize totally ergodic rank-1 transformations with bounded cutting parameter. Together with a recent result of Ryzhikov, our results provide a simple procedure for determining, purely in terms of the cutting and spacer parameters for the transformation, whether a bounded rank-1 transformation has minimal self-joinings of all orders.
