Oliver Bendel,Nick Lin-Hi,Andreas Suchaneknce of the orthogonal projections onto invariant subspaces of the operators A and B = A + V. These results extend the celebrated Davis-Kahan tan 2Θ Theorem. On this basis we also prove new existence and uniqueness theorems for contractive solutions to the operator Riccati equation, thus, extending recent results of Adamyan, Langer, and Tretter.

The Schur Algorithm for Generalized Schur Functions IV: Unitary Realizations,tain one-sidedness is replaced by a two-sidedness, comparable to the difference between the unilateral shift on one-sided sequences and the shift on two-sided sequences. We follow a direct approach in line with [., ., .].

Rational Solutions of the Schlesinger System and Isoprincipal Deformations of Rational Matrix Functnverse is also true in the non-resonant case, but not in general..In the forthcoming sequel we shall give an explicit description of a class of rational solutions of the Schlesinger system, based on the techniques developed here, and the realization theory for rational matrix functions.
