On Toeplitz and Wiener-Hopf Operators with Contourwise Rational Matrix and Operator Symbols
Israel Gohberg,Marinus A. Kaashoek,Leonid Lerer,Leiba Rodman +3 more
- 01 Jan 1986
TL;DR: In this article, the authors consider operators with symbols defined on a curve composed of several non-intersecting simple closed contours and present criteria and explicit formulas for canonical factorization of matrix functions relative to a compound contour.

Second order parallel algorithms for Fredholm integral equations with continuous displacement kernels
TL;DR: Parallel algorithms with second order precision are derived for efficient numerical solution of Fredholm integral equations of the second kind with displacement kernels.

Pairs of shift invariant subspaces of matrices and noncanonical factorization
Joseph A. Ball,Israel Gohberg +1 more
TL;DR: In this paper, the set of pairs of shift invariant subspaces, find the invariants and simplest representative of each class, is analyzed for different types of LU factorizations with a middle factor.

Left and right factorizations of rational matrix functions
Israel Gohberg,Y. Zucker +1 more
TL;DR: In this article, the right partial indices of the symbol are described in terms of realizations of factors of the left Wiener-Hopf canonical factorization of the same symbol.

Second order parallel algorithms for piecewise smooth displacement kernels
TL;DR: Two second order parallel algorithms for Fredholm integral equations with piecewise smooth displacement kernels are derived based on a difference scheme of Runge-Kutta type for an unusual partial differential equations for continuous functions of two variables.
