与循环流有关的稳定平稳过程

Stable stationary processes related to cyclic flows

Vladas Pipiras, Murad S. Taqqu

摘要:

我们研究平稳稳定的过程有关的周期性和循环流的意义上的Rosinski [安。23(1995)1163-1187]。这些过程不是遍历的。我们提供了他们的规范表示,考虑的例子,并显示如何识别它们之间的一般平稳稳定过程。我们的结论与唯一的分解在分布的平稳稳定过程的四个主要的独立分量之和:1。混合移动平均线成分。2.可协调的(或"琐碎的“)成分。3.循环成分4.与这些不同的组件。

英文摘要:

We study stationary stable processes related to periodic and cyclic flows in the sense of Rosinski [Ann. Probab. 23 (1995) 1163-1187]. These processes are not ergodic. We provide their canonical representations, consider examples and show how to identify them among general stationary stable processes. We conclude with the unique decomposition in distribution of stationary stable processes into the sum of four major independent components: 1. A mixed moving average component. 2. A harmonizable (or ``trivial'') component. 3. A cyclic component 4. A component which is different from these.
