Circulant integral operators as preconditioners for Wiener-Hopf equations
Integral Equations and Operator Theory, 1995The authors study the solution of the Wiener-Hopf equation \((\sigma I + K) x = g\), where the integral operator \((Kx)(t) = \int^\infty_0 k(t - s) x(s) ds\) is self adjoint and positive definite, \(k \in L_1(- \infty, \infty)\), \(g \in L_2(0,\infty)\), \(\sigma > 0\), by the preconditioned conjugate gradient method. A scheme of constructing circulant

Wiener-Hopf Integral Equations
2000The purpose of this chapter is to study the distributional solution of the integral equations of the type $$g(x) + \lambda \int_{0}^{\infty } {k(x - y)g(y)dy = f(x), x \geqslant 0}$$ (8.1) , as well as the corresponding equations of the first kind, the so-called Wiener-Hopf integral equations.

Wiener-Hopf Integral Equations, Toeplitz Matrices and Linear Systems
1982This paper contains a new method to solve Wiener-Hopf integral equations, which employs explicitly connections with linear systems. These connections are based on a special exponential operator representation of the kernel of the integral equation whose Fourier transform is analytic on the real line and at infinity. With this approach explicit formulas

The Wiener--Hopf Integral Equation in the Supercritical Case
Mathematical Notes, 2004The author studies an asymptotic behavior of the solutions of the homogeneous Wiener-Hopf integral equation \(S(x)=\int_0^\infty K(x-t)S(t) \,dt\), \(x>0,\) with smooth nonnegative even kernel \(K(x)\) such that \(K^{\prime}(x)\leq 0, K^{\prime\prime}(x)\geq 0,\) and \(K^{\prime\prime}(x) \downarrow \) on \(R^+\).

Nystrom-Product Integration for Wiener-Hopf Equations with Applications to Radiative Transfer
IMA Journal of Numerical Analysis, 1989This paper presents a numerical solution of the Wiener-Hopf integral equation \(u(x)-\int^{\infty}_{\beta}K(x-t)u(t)dt=f(x),\) where \(K(x)\) has logarithmic singularity at \(x=0\), and decays exponentially as \(| x| \to \infty\). An approximate solution \(u_ n\) is defined by introducing a mesh with \(n\) subintervals on \([0,\infty)\), and then ...

A generalized approach to solving Fredholm and Wiener-Hopf integral equations
1970 IEEE Symposium on Adaptive Processes (9th) Decision and Control, 1970A generalized method is presented for the solution of Fredholm and Wiener-Hopf integral equations using the theory of distributions. By separating the integral through determination of the limits of integration, bounded linear differential operators may be defined which reduce the integral equation problem to one of solving a distributional ...

Wiener — Hopf Integral Equations: Finite Section Approximation and Projection Methods
1985We consider the numerical solution of integral equations on the half-line by their finite-section approximation and by projection methods. Convergence results for the finite-section approximation are discussed, and are shown to be important in the analysis of the convergence of the projection method.
