摘要：

The theory of finite-dimensional perturbations of self-adjoint operators, which is aimed at the solution of physical problems, is reviewed. Special attention is paid to the special kind of operators, which permits efficient application of the J-matrix technique. The spectral density of a periodic J-matrix is calculated. (C) 1997 American Institute of Physics.
