摘要:

本文致力于基于广义迭代傅里叶级数点wise收敛来展开任意乘数k(k∈N)的迭代斯特拉托维奇随机积分。详细讨论了傅里叶-勒贝格级数以及三角傅里叶级数的情况。所获得的展开式提供了将迭代斯特拉托维奇随机积分表示为标准高斯随机变量乘积迭代级数的可能性。证明了展开式在均值平方度2n(n∈N)下的收敛性。给出了关于乘数3到6的迭代斯特拉托维奇随机积分展开的一些最新结果。本文的结果可以应用于伊藤随机微分方程的数值求解。

英文摘要:

The article is devoted to the expansion of iterated Stratonovich stochastic integrals of arbitrary multiplicity $k$ $(k\in\mathbb{N})$ based on the generalized iterated Fourier series converging pointwise. The case of Fourier-Legendre series as well as the case of trigonometric Fourier series are considered in details. The obtained expansion provides a possibility to represent the iterated Stratonovich stochastic integral in the form of iterated series of products of standard Gaussian random variables. Convergence in the mean of degree $2n$ $(n\in \mathbb{N})$ of the expansion is proved. Some recent results on the expansion of iterated Stratonovich stochastic integrals of multiplicities 3 to 6 are given. The results of the article can be applied to the numerical solution of Ito stochastic differential equations.
