Block matrices corresponding to the strong two-dimensional real moment problem

UDC 517.98 We generalize the relationship between the strong one-dimensional real moment problem and the spectral theory of  Jacobi-type  block matrices for the two-dimensional case. An analog of Jacobi-type matrices corresponding to the problem in this formulation is proposed, and the corresponding...
