If one assurnes that the function does not have a pole or a zero at infinity, the formula which solves this problem is (1) where Zl , Z/ are the…

Kaashoek, Bitangential interpola tion for input-output operators of time varying systems: the discrete time case contains solutions of time varying interpolation problems.

This volume contains a selection of papers on modern operator theory and its applications, arising from a joint workshop on linear one-dimensional singular integral equations. The book is of interest…

Schur analysis originated with an 1917 article which associated to a function, which is analytic and contractive in the open unit disk, a sequence, finite or infinite, of numbers in…

This volume is dedicated to Tsuyoshi Ando, a foremost expert in operator theory, matrix theory, complex analysis, and their applications, on the occasion of his 60th birthday. This volume also…

In this article we shall use two special classes of reproducing kernel Hilbert spaces (which originate in the work of de Branges [dB) and de Branges-Rovnyak [dBRl), respectively) to solve…

he visits his neighbour Harry Dym at the Weizmann Institute regularly, he spends several months a year in Amsterdam working with Rien Kaashoek, several weeks in Maryland with Seymour Goldberg…

In this book we study orthogonal polynomials and their generalizations in spaces with weighted inner products. These ortho gonal polynomials are called the Szego polynomials associated with the weight w.
