Abstract: The matrix Schrödinger operator with point interactions on the semiaxis is studied. Using the theory of boundary triplets and the corresponding Weyl functions, we establish a relationship between the spectral properties (deficiency indices, self-adjointness, semiboundedness, etc.) of the operators under study and block Jacobi matrices of certain class.
Keywords: Schrödinger operator, Jacobi matrix, delta-interaction, self-adjointness, deficiency index.
