我们定义了秩一变换中的正则有界性的概念,并用它来刻画了一类具有平凡中心化器的所有有界秩一变换。我们还明确地描述了具有有界切割参数的全遍历秩一变换。与Ryzhikov最近的结果一起,我们的结果提供了一个简单的过程来确定一个有界的秩一变换是否具有所有阶的最小自连接,纯粹是根据变换的切割和间隔参数。
We define the notion of canonical boundedness among rank-one transformations and use it to characterize the class of all bounded rank-one transformations with trivial centralizer. We also explicitly characterize totally ergodic rank-one transformations with bounded cutting parameter. Together with a recent result of Ryzhikov our results provide a simple procedure for determining whether a bounded rank-one transformation has minimal self-joinings of all orders purely in terms of the cutting and spacer parameters for the transformation.
