Canonical Wiener-Hopf factorization on the unit circle: matching subspaces versus Riccati equations
Sanne ter Horst, Mikael Kurula, Andre Ran
Wiener-Hopf factorization is an important tool in the study of block Toeplitz and block Wiener-Hopf operators, and many applications involving these operators. In this paper we com…
Optimal interpolation in Hardy and Bergman spaces: a reproducing kernel Banach space approach
Gilbert J. Groenewald, Sanne ter Horst, Hugo J. Woerdeman
After a review of the reproducing kernel Banach space framework and semi-inner products, we apply the techniques to the setting of Hardy spaces and Bergman spaces , $1<p…
Indefinite determinantal representations versus nonsingularities on the noncommutative d-torus
Gilbert J. Groenewald, Sanne ter Horst, Hugo J. Woerdeman
We show that for a multivariable polynomial with a determinantal representation the matrix $…
Realization theory for poset-causal systems: Controllability, observability and duality
Sanne ter Horst, Jaccie Zeelie
Poset-causal systems form a class of decentralized systems introduced by Shah and Parrilo [32] and studied mainly in the context of optimal decentralized control. In this paper we…
Multivariable operator-valued Nevanlinna-Pick interpolation: a survey
J. A. Ball, S. ter Horst
The theory of Nevanlinna-Pick and Carathéodory-Fejér interpolation for matrix- and operator-valued Schur class functions on the unit disk is now well established. Recent work has p…
