Two-dimensional moment problem and Schur algorithm
<|reference_start|>Two-dimensional moment problem and Schur algorithm: 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 on the continued fraction expansion of the solution. In particular, the obtained results are applicable to the two-dimensional moment problem for atomic measures.<|reference_end|>
