A Potapov-type approach to a truncated matricial Stieltjes-type power moment problem
B. Fritzsche, B. Kirstein, C. Mädler +1
The paper gives a parametrization of the solution set of a matricial Stieltjes-type truncated power moment problem in the non-degenerate and degenerate cases. The key role plays th…
An Application of the Schur Complement to Truncated Matricial Power Moment Problems
Bernd Fritzsche, Bernd Kirstein, Conrad Mädler
The main goal of this paper is to reconsider a phenomenon which was treated in earlier work of the authors' on several truncated matricial moment problems. Using a special kind of…
Duality results for a general trigonometric approximation problem
Lutz Klotz, Conrad Mädler
Let and be a regular finite Borel measure on a locally compact abelian group. The paper deals with a general trigonometric approximation problem in , w…
On the truncated matricial Stieltjes moment problem
Bernd Fritzsche, Bernd Kirstein, Torsten Schröder +1
This paper gives via Stieltjes transform a complete description of the solution set of a matricial truncated Stieltjes-type power moment problem in the non-degenerate and degenerat…
On the structure of Hausdorff moment sequences of complex matrices
Bernd Fritzsche, Bernd Kirstein, Conrad Mädler
The paper treats several aspects of the truncated matricial -Hausdorff type moment problems. It is shown that each -Hausdorff moment sequence has a particular intrins…
On a Simultaneous Approach to the Even and Odd Truncated Matricial Stieltjes Moment Problem II. An -Schur-Stieltjes-type algorithm for sequences of holomorphic matrix-valued functions
Bernd Fritzsche, Bernd Kirstein, Conrad Mädler
The main goal of this paper is to achieve a simultaneous treatment of the even and odd truncated matricial Stieltjes moment problems in the most general case. These results are gen…
