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.
