The strong Hamburger moment problem and related direct and inverse spectral problems for block Jacobi-Laurent matrices

Abstract

In this article we propose an approach to the strong Hamburger moment problem based on the theory of generalized eigenvectors expansion for a selfadjoint operator. Such an approach to another type of moment problems was given in our works earlier, but for strong Hamburger moment problem it is new. We get a sufficiently complete account of the theory of such a problem, including the spectral theory of block Jacobi-Laurent matrices.

Key words: Classical and strong moment problems, block three-diagonal matrix, eigenfunction expansion, generalized eigenvector.
