Abstract:
Necessary and sufficient conditions for the Stieltjes moment problem to have a unique solution and for the Hamburger moment problem with the same moments to have infinitely many solutions were obtained in Hamburger's papers on the classical moment problem. In this paper, we obtain an analog of Hamburger's criterion for the matrix moment problem.
Keywords:
Hamburger moment problem, Stieltjes moment problem, Hermitian matrix, matrix function, block matrix.
