Abstract
For pt.II see ibid., vol.11, p.1501 (1978). Suggests constructing an inverse of the infinite-dimensional matrix Q by means of its recurrent algebraic decomposition into the easily invertible two-diagonal factors. The merits and feasibility of the method are illustrated on the five-diagonal matrices. Quartic and decadic-decadic anharmonic propagators are chosen as examples of the application.Keywords
