UDC 517.9 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 $l_2$-like space as commuting...
