均匀迁移过程对布朗单的强逼近

Strong approximations of Brownian sheet by uniform transport processes

Xavier Bardina, Marco Ferrante, Carles Rovira

摘要:

许多年前,Griego,Heath和Ruiz-Moncayo证明了可以定义一系列一致变换过程的实现,这些过程几乎必然收敛于标准的布朗运动,并且在单位时间间隔上一致。本文将他们的结果推广到多参数情形。我们开始构建一个家庭的过程,从一组独立的标准泊松过程,实现几乎肯定收敛到布朗单,一致的单位平方。最后给出了$d$ -参数Wiener过程的推广.

英文摘要:

Many years ago, Griego, Heath and Ruiz-Moncayo proved that it is possible to define realizations of a sequence of uniform transform processes that converges almost surely to the standard Brownian motion, uniformly on the unit time interval. In this paper we extend their results to the multi parameter case. We begin constructing a family of processes, starting from a set of independent standard Poisson processes, that has realizations that converge almost surely to the Brownian sheet, uniformly on the unit square. At the end the extension to the $d$-parameter Wiener processes is presented.
