摘要:

本文构造了重数为1 ~ 5的Stratonovich迭代随机积分的均方逼近的有效方法。本文将广义多重傅里叶级数方法应用于迭代随机积分的逼近。更准确地说,我们使用多个Fourier-Legendre级数收敛在希尔伯特空间$L_2([t,T]^k),$ $k\in\mathbb{N}.$考虑迭代Stratonovich随机积分的Taylor-Stratonovich展开的一部分。这就是为什么本文的结果可以应用于实现的Ito随机微分方程与多维非交换噪声的1.0,1.5,2.0和2.5阶强收敛的数值方法。

英文摘要:

The article is devoted to construction of effective procedures of the mean-square approximation for iterated Stratonovich stochastic integrals of multiplicities 1 to 5. We apply the method of generalized multiple Fourier series for approximation of iterated stochastic integrals. More precisely, we use multiple Fourier-Legendre series converging in the sense of norm in Hilbert space $L_2([t,T]^k),$ $k\in\mathbb{N}.$ Considered iterated Stratonovich stochastic integrals are part of the Taylor-Stratonovich expansion. That is why the results of the article can be applied to implementation of numerical methods with the orders 1.0, 1.5, 2.0 and 2.5 of strong convergence for Ito stochastic differential equations with multidimensional non-commutative noise.
