Minimal Factorization, Linear Systems and Integral Operators, lecture the emphasis is on minimal factorization of linear time invariant systems. Wiener-Hopf integral equations with matrix-valued kernels form the main topic of the second lecture. The classical approach to such equations is combined with the method of factorization discussed in the first lectur

Ha-Plitz Operators: A Survey of Some Recent Results,ively, difference of indices: ., .. Many close relations of such operators (matrices) to various problems of algebra, analysis, differential equations were discovered as early as in the last century. But the spectral theories of Hankel and Toeplitz operators start their development only in the late

Stochastic Processes, Infinitesimal Generators and Function Theory,’s solution in 1944 [22 ] of the Dirichlet problem by using Brownian motion. Subsequently many other striking connections have been found and they have been extended to general Markov processes and associated harmonic spaces. See e.g. Constantinescu & Cornea [ 5 ] and Bliedtner & Hansen [ 3].

Operator-Theoretic Aspects of the Nevanlinna-Pick Interpolation Problem,tion obeying a prescribed bound. These lectures are intended to bring out certain operator-theoretic aspects of that problem. Two approaches to the problem will be discussed, the original function-theoretic one of R. Nevanlinna and a recent operator-theoretic one due to J. A. Ball and J. W. Helton.

Cyclic Vectors in Banach Spaces of Analytic Functions,n it is of interest to describe the cyclic vectors for this operator, that is, those functions in the space with the property that the polynomial multiples of the function are dense. A necessary condition is that the function have no zeros; in general it is difficult to give necessary and sufficient

Interpolation by Analytic Matrix Functions,One reason for this is strictly mathematical; the development of certain branches of operator theory has enabled us to view the problems in a different way and so understand some aspects of them better. There is another reason, which for me rings an even louder bell: contact with the theory of circu

Minimal Factorization, Linear Systems and Integral Operators,ms of inversion and decoupling of systems. The main part of the work reported on is joint work (in different groupings) with H. Bart, I. Gohberg, F. van Schagen and P. Van Dooren. It is a pleasure to thank I. Gohberg for several discussions about the plan for these lectures.
