We describe the direct and inverse spectral problems related to the block Jacobi type matrices that correspond to the two-dimensional half-strong real moment problem.
In particular, we obtain three matrices that have three-diagonal block structure and act in an l2-like space as commuting self-adjoint operators, and two of them are mutually inverse.
