Multidimensional moment problem and Stieltjes transform
Ivan Kovalyov
The truncated multidimensional moment problem is studied in terms of the Stieltjes transform as the interpolation problem. A step-by-step algorithm is constructed for the multidime…

Two-dimensional moment problem and Schur algorithm
Ivan Kovalyov, Stefan Kunis
We study a truncated two-dimensional moment problem in terms of the Stieltjes transform. The set of the solutions is described by the Schur step-by-step algorithm, which is based o…
