Characteristic Function, Schur Parameters and Pseudocontinuation of Schur functions
Vladimir K. Dubovoy, Bernd Fritzsche, Bernd Kirstein +2
In [19] there is an approach to the investigation of the pseudocontinuability of Schur functions in terms of Schur parameters. In particular, there was obtained a criterion for the…
Characteristic Function, Schur Interpolation Problem and Darlington Synthesis
Sergey S. Boiko, Vladimir K. Dubovoy, Bernd Fritzsche +3
In this paper we would like to show the interrelation between the different mathematical theories concerning the Schur interpolation problem, contractions in Hilbert spaces, pseudo…
The Weyl matrix balls corresponding to the matricial truncated Hamburger moment problem
Bernd Fritzsche, Bernd Kirstein, Susanne Kley +1
The main goal of the paper is to parametrize the Weyl matrix balls associated with an arbitrary matricial truncated Hamburger moment problem. For the special case of a non-degenera…
block representations of the Moore-Penrose inverse and orthogonal projection matrices
Bernd Fritzsche, Conrad Mädler
In this paper, new block representations of Moore-Penrose inverses for arbitrary complex block matrices are given. The approach is based on block representations of orth…
A Schur-Nevanlinna type algorithm for the truncated matricial Hausdorff moment problem
Bernd Fritzsche, Bernd Kirstein, Conrad Mädler
The main goal of this paper is to achieve a parametrization of the solution set of the truncated matricial Hausdorff moment problem in the non-degenerate and degenerate situation.…
Schur analysis of matricial Hausdorff moment sequences
Bernd Fritzsche, Bernd Kirstein, Conrad Mädler
We develop the algebraic instance of an algorithmic approach to the matricial Hausdorff moment problem on a compact interval of the real axis. Our considerations are along…
