Distribution of Zeros of Orthogonal Functions Related to the Nehari Problem
Robert L. Ellis,Israel Gohberg +1 more
TL;DR: In this paper, the authors prove continuous analogues of results concerning the distribution of zeros of orthogonal matrix functions related to the Nehari problem in the context of matrix functions.
Book ChapterDOI
Boundary Nevanlinna-Pick Interpolation
TL;DR: In this article, a variant of the Nevanlinna-pick interpolation problem is studied, where one seeks a function analytic and bounded by 1 on a domain which meets a set of interpolation conditions, some of which may now be prescribed on the boundary of the domain.
BookDOI
New aspects in interpolation and completion theories
TL;DR: In this paper, the authors considered the problem of bitangential interpolation for input-output operators of time-varying systems and proposed a generalization of the Nevanlinna pick problem.

The Bezout integral operator: main property and underlying abstract scheme. The state space method generalizations and applications
TL;DR: In this article, a continuous analogue of the classical Bezout matrix for scalar polynomials is introduced and studied, which is an integral operator with a matrix-valued kernel.
