On maximum entropy interpolants and maximum determinant completions of associated Pick matrices
Harry Dym,Israel Gohberg +1 more
TL;DR: In this article, it was shown that the value of the maximum ω-entropy solution of an interpolation problem of the Nevanlinna-Pick type at the point ω maximizes the determinant of the solution of the associated matrix completion problem.
Journal ArticleDOI
A sign characteristic for selfadjoint meromorphic matrix functions
TL;DR: The notion of sign characteristic for self-adjoint meromorphic matrix functions was introduced in this paper, which generalizes this notion for matrix polynomials introduced by the authors in [4].
Journal ArticleDOI
On explicit factorization and applications
TL;DR: The first application is concerned with explicit factorization of a class of matrices of Daniel-Khrapkov type and the second is related to inversion of finite Toeplitz matrices.
Journal ArticleDOI
Finite dimensional Wiener-Hopf equations and factorizations of matrices
Israel Gohberg,Seymour Goldberg +1 more
TL;DR: In this article, the authors investigated the Wiener-Hopf equation P ( ax + ) = y +, where y + ∈ A + is given and x +∈ A+ is a solution.
Journal ArticleDOI
Similarity and reduction for time varying linear systems with well posed boundary conditions
Israel Gohberg,M A Kaashoek +1 more
TL;DR: In this article, the classical theory of similarity and reduction of causal and anti-causal systems is generalized and extended to time varying linear systems with well-posed boundary conditions, and two main problems are solved.
