The Wiener–Hopf Equation with Probability Kernel and Submultiplicative Asymptotics of the Inhomogeneous Term

AppliedMath, 2022
We consider the inhomogeneous Wiener–Hopf equation whose kernel is a nonarithmetic probability distribution with positive mean. The inhomogeneous term behaves like a submultiplicative function.

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

Journal 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.

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

Journal 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.

Solvability of a class of set-valued implicit quasi-variational inequalities: A Wiener–Hopf equation method

Results in Control and Optimization, 2022
In this paper, we consider a class of set-valued implicit quasi-variational inequalities in real Banach spaces and show its equivalence with a class of fixed point equations and a class of Wiener–Hopf equations.

An antiplane crack emerging from the top of a composite functional gradient wedge

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023
In the paper, the problem on an interface longitudinal shear crack located between two functionally graded wedge-shaped regions and emerging from their common vertex has been considered.

Network representations of angular regions for electromagnetic scattering. [PDF]

PLoS ONE, 2017
Network modeling in electromagnetics is an effective technique in treating scattering problems by canonical and complex structures. Geometries constituted of angular regions (wedges) together with planar layers can now be approached with the Generalized ...

La factorización de una transformada de Fourier en el método de Wiener-Hopf

Revista de Matemática: Teoría y Aplicaciones, 2009
Using the Wiener-Hopf method, we factorize the Fourier Transform of the kernel of a singular integral equation as the product of two functions: one holomorphic in the upper semiplan and the other holomophic in the lower semiplan.

Functionally graded wedge weakened by a semi-infinite crack

St. 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.
