Abstract
We study two classes of Jacobi matrices that have arisen in connection with the investigation of operators with point interactions. New conditions for self-adjointness and maximal deficiency indices of block Jacobi matrices are obtained. New conditions for the discreteness of the spectrum of the Schrödinger and Dirac operators with point interactions are found.
