Wiener-Hopf(WH)方法由Norbert Wiener和Eberhard Hopf于1931年创立,用于求解半直线上具有卷积型核的积分方程解。这个问题似乎与Riemann在1857年提出的关于构造具有给定奇点和指定单调群的Fuchsian微分方程组的问题密切相关。这后来被称为21世纪的希尔伯特问题。由于解析函数的本质特征,WH方法是一种强大而由来已久的工具,在扩大傅立叶分析的适用性方面起到了催化剂的作用。将傅里叶变换(FT)用于积分方程导出实轴上的黎曼-希尔伯特(RH)问题:+(S)+K(S)−(S)=G(S),S∈R,(1)其中S是FT参数,G是指定函数,+,−是未知函数,只是上标表示它们分别是Im(S)>0,Im(S)<0的解析函数。该方法的一个基本组成部分是将给定的核分解成如下形式:K(S)=K+(S)K−(S),其中K±(S)是±Im(S)>0的解析非零函数。
The Wiener-Hopf (WH) method was created in 1931, by Norbert Wiener and Eberhard Hopf, to deliver exact solutions to integral equations with convolutiontype kernels on a half-line. It appears that this problem is closely related to that posed by Riemann in 1857 on the problem concerning the construction of a Fuchsian system of differential equations with given singular points and a prescribed monodromy group. This later became known as the 21st Hilbert problem. The WH method is a powerful and long-standing tool that served as a catalyst in broadening the applicability of Fourier analysis, owing to the essential characteristics of analytic functions. Employing the Fourier transform (FT) to the integral equation leads to a Riemann-Hilbert (RH) problem on the real axis:+(s)+ K (s)−(s)= G (s), s∈ R,(1) where s is the FT parameter, G is a specified function and+,− are unknown functions except that the superscript indicates they are analytic for Im (s)> 0, Im (s)< 0, respectively. An essential component of the method is to factorize the given kernel into the form: K (s)= K+(s) K−(s), where K±(s) are analytic and nonvanishing functions for±Im (s)> 0.
