Stress Concentrations in Non-Homogeneous Elastic Layer Weakened by Cracks
Engineering Transactions, 1979 The paper presents the statical problem of stress concentrations around the tips of two semi-infinite cracks situated within an infinite, non-homogenous elastic layer. The conditions of antiplane state of strain are assumed to be satisfied.

On Wiener-Hopf Determinants [PDF]
, 1989 Any extension of the “strong” limit theorem for Toeplitz determinants to continuous convolution operators requires an assumption that allows one to define the determinant in question. In this paper a natural assumption on a matrix-valued symbol is presented which guarantees that the regularized determinant det(p) is defined, and a limit theorem for it ...

Iterative Algorithms for General Multivalued Variational Inequalities
Abstract and Applied Analysis, 2012 We introduce and study some new classes of variational inequalities and the Wiener-Hopf equations. Using essentially the projection technique, we establish the equivalence between these problems.

A global description of solutions to nonlinear perturbations of the Wiener-Hopf integral equations
Electronic Journal of Differential Equations, 2006 We establish the solvability, the number of solutions and the covering dimension of the solution set of nonlinear Wiener-Hopf equations. The induced linear mapping is assumed to be of nonnegative index, while the nonlinearities are such that ...

Wiener Filter Using the Conjugate Gradient Method and a Third-Order Tensor Decomposition
Applied SciencesIn linear system identification problems, the Wiener filter represents a popular tool and stands as an important benchmark. Nevertheless, it faces significant challenges when identifying long-length impulse responses.

On a Wiener-Hopf Integral Equation
Journal of Integral Equations and Applications, 1995 The author considers the following problem: determine the positive sequence \(\{E_n\}\) satisfying the infinite discrete system \[ \sin \left( {\pi \over 4} + \theta \right) \sum_{n = 0}^\infty {E_n \over \beta_n - \theta} + \sin \left( {\pi \over 4} - \theta \right) \sum^\infty_{n = 0} {E_n \over \beta_n + \theta} = \sqrt 2 {\sin \theta \over \theta} \

Wiener-Hopf Theory and Nonunimodular Groups
Journal of Functional Analysis, 1994 Let \(G\) be a connected real nonunimodular (i.e. the modular function \(m(g) \not\equiv 1)\) Lie group. Let \(X_0, \dots, X_k\) be the left invariant fields on \(G\), let \(\Delta = \sum_{j \geq 1} X^2_j + X_0\) and \(T_t = e^{-t \Delta}\) be the left Laplacian and the left diffusion semigroup, respectively.
