On the two-dimensional moment problem. (English)
[J] Ann. Funct. Anal. AFA 1, No. 1, 80-104, electronic only (2010). ISSN 2008-8752/e

The two-dimensional moment problem consists of finding a non-negative Borel measure $\mu$ in ${\mathbb R}^{2}$ such that $$ \int_{\mathbb R^{2}} x_{1}^{m}x_{2}^{n}\,d\mu=s_{m,n}, \quad m,n\in\mathbb Z_{+} $$ where $\{s_{m,n}\}_{m,n\in\mathbb Z_{+}}$ is prescribed sequence of complex numbers. The author obtains an algorithm to solve the two-dimensional moment problem. The algorithm gives the necessary and sufficient conditions for the solvability of the moment problem. In addition, analogous results are obtained for the complex moment problem.
