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…

A new systems theory perspective on canonical Wiener-Hopf factorization on the unit circle
Sanne ter Horst, Mikael Kurula, André Ran
We establish left and right canonical factorizations of Hilbert-space operator-valued functions G(z) that are analytic on neighborhoods of the complex unit circle and the origin 0,…
