平稳高斯过程的能级交叉和其它能级泛函

Level crossings and other level functionals of stationary Gaussian processes

Marie F. Kratz

摘要:

本文提出了一个综合的平稳高斯过程的水平交叉的数学工作,与一些扩展。主要结果[(阶乘)的时刻,表示到维纳混沌,渐近结果,收敛速率,当地时间和交叉数]进行了说明,以及不同的方法[正常比较法,赖斯方法,斯坦陈方法,一般$m$依赖的方法]用于获得它们,这些方法也是非常有用的一般情况下的高斯场。最后,提出了一些扩展[时间占用泛函,在一个区间内的最大值的数量,由二维集索引的过程],说明了方法的通用性。一个关于这个问题的大量论文和书籍的库存结束了调查。

英文摘要:

This paper presents a synthesis on the mathematical work done on level crossings of stationary Gaussian processes, with some extensions. The main results [(factorial) moments, representation into the Wiener Chaos, asymptotic results, rate of convergence, local time and number of crossings] are described, as well as the different approaches [normal comparison method, Rice method, Stein-Chen method, a general $m$-dependent method] used to obtain them; these methods are also very useful in the general context of Gaussian fields. Finally some extensions [time occupation functionals, number of maxima in an interval, process indexed by a bidimensional set] are proposed, illustrating the generality of the methods. A large inventory of papers and books on the subject ends the survey.
