  • Orthogonal Matrix-Valued Polynomials and Applications
    I. Gohberg
    This paper is a largely expository account of the theory of p x p matrix polyno­ mials associated with Hermitian block Toeplitz matrices and some related problems of interpolation and extension. Perhaps the main novelty is the use of reproducing kernel Pontryagin spaces to develop parts of the theory in what hopefully the reader will regard as a reaso...

  • Topics in Interpolation Theory of Rational Matrix-Valued Functions
    I. Gohberg
    One of the basic interpolation problems from our point of view is the problem of building a scalar rational function if its poles and zeros with their multiplicities are given. 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 given zeros with given mult...

  • Interpolation of Rational Matrix Functions
    I. Gohberg / Joseph A. Ball / Rodman
    This book aims to present the theory of interpolation for rational matrix functions as a recently matured independent mathematical subject with its own problems, methods and applications. The authors decided to start working on this book during the regional CBMS conference in Lincoln, Nebraska organized by F. Gilfeather and D. Larson. The principal le...

  • Metric Constrained Interpolation, Commutant Lifting and Systems
    A.E. Frezho / C. Foias / I. Gohberg
    This book presents a unified approach for solving both stationary and nonstationary interpolation problems, in finite or infinite dimensions, based on the commutant lifting theorem from operator theory and the state space method from mathematical system theory. Initially the authors planned a number of papers treating nonstationary interpolation probl...
