非线性高斯泛函的Wick演算

Wick Calculus For Nonlinear Gaussian Functionals

Yaozhong Hu, Jia-an Yan

摘要:

本文综述了Wick乘积和Wick重整化的一些结果。框架是抽象的维纳空间。给出了经典随机变量在白噪声分析框架下的Wick乘积和Wick重整化的一些已知结果。给出了随机变量的Wick积或重正化是可积随机变量的一些条件。本文还简要地介绍了多重Wiener积分、二次量子化算子、Malliavin积分及其与Wick乘积和Wick重整化的关系。Wick乘积的一个有用的工具是$S$ -变换,它也是在不引入广义随机变量的情况下描述的。

英文摘要:

This paper surveys some results on Wick product and Wick renormalization. The framework is the abstract Wiener space. Some known results on Wick product and Wick renormalization in the white noise analysis framework are presented for classical random variables. Some conditions are described for random variables whose Wick product or whose renormalization are integrable random variables. Relevant results on multiple Wiener integrals, second quantization operator, Malliavin calculus and their relations with the Wick product and Wick renormalization are also briefly presented. A useful tool for Wick product is the $S$-transform which is also described without the introduction of generalized random variables.
