Solvability of an Integral Equation of Volterra-Wiener-Hopf Type [PDF]

open access: yesAbstract and Applied Analysis, 2014
The paper presents results concerning the solvability of a nonlinear integral equation of Volterra-Stieltjes type. We show that under some assumptions that equation has a continuous and bounded solution defined on the interval 0,∞ and having a finite ...

Numerical solution of scattering problems using a Riemann-Hilbert formulation. [PDF]

open access: yesProc Math Phys Eng Sci, 2019
A fast and accurate numerical method for the solution of scalar and matrix Wiener--Hopf problems is presented. The Wiener--Hopf problems are formulated as Riemann--Hilbert problems on the real line, and a numerical approach developed for these problems ...

Running coupling and non-perturbative corrections for O(N) free energy and for disk capacitor

open access: yesJournal of High Energy Physics, 2022
We reconsider the complete solution of the linear TBA equation describing the energy density of finite density states in the O(N) nonlinear sigma models by the Wiener-Hopf method.

Operational Quadrature Methods for Wiener-Hopf Integral Equations [PDF]

open access: yesMathematics of Computation, 1993
We study the numerical solution of Wiener-Hopf integral equations by a class of quadrature methods which lead to discrete Wiener-Hopf equations, with quadrature weights constructed from the Fourier transform of the kernel (or rather, from the Laplace transforms of the kernel halves).

Reproducing kernel method for solving wiener-hopf equations of the second kind [PDF]

open access: yesJournal of Hyperstructures, 2016
This paper proposed a reproducing kernel method for solving Wiener-Hopf equations of the second kind. In order to eliminate the singularity of the equation, a transform is used.

Functionally graded wedge weakened by a semi-infinite crack

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022
In the paper, the problem of a semi-infinite antiplane interface crack located between two functionally graded wedge-shaped regions has been considered. The shear modules of the materials’ regions are quadratic functions of the polar angle.
