多维Kingman-Lévy过程的涨落

Fluctuations of Multi-Dimensional Kingman-LÉvy Processes

Thu Nguyen

摘要:

在最近的论文\cite{Ng5}中,我们介绍了一种研究多维Kingman卷积及其相关随机过程的方法,即把它们嵌入到多维普通卷积中,从而可以用相应的布朗运动来研究多维Bessel过程.本文的进一步目的是引入k维Kingman-Lévy(KL)过程,并证明其类似于k-对称Lévy过程的某些涨落性质。特别地,得到了k维KL-过程的Lévy-Itô分解和Rosienski型级数表示.

英文摘要:

In the recent paper \cite{Ng5} we have introduced a method of studying the multi-dimensional Kingman convolutions and their associated stochastic processes by embedding them into some multi-dimensional ordinary convolutions which allows to study multi-dimensional Bessel processes in terms of the cooresponding Brownian motions. Our further aim in this paper is to introduce k-dimensional Kingman-Lévy (KL) processes and prove some of their fluctuation properties which are analoguous to that of k-symmetric Lévy processes. In particular, the Lévy-Itô decomposition and the series representation of Rosiński type for k-dimensional KL-processes are obtained.
