非奇异群作用与平稳S α S随机场

Nonsingular Group Actions and Stationary S alpha S Random Fields

Parthanil Roy

摘要:

本文研究了R^d指标的可测平稳对称稳定随机场及其与非奇异R^d作用量的遍历论的关系。在Rosinski(2000)的唯象工作的基础上,我们将平稳S α S过程的一些结构结果推广到SαS场.根据基本作用的遍历理论性质,我们观察到场的极端的不同行为。

英文摘要:

This paper deals with measurable stationary symmetric stable random fields indexed by R^d and their relationship with the ergodic theory of nonsingular R^d-actions. Based on the phenomenal work of Rosinski(2000), we establish extensions of some structure results of stationary S alpha S processes to SαS fields. Depending on the ergodic theoretical nature of the underlying action, we observe different behaviors of the extremes of the field.
