| description | Time-independent perturbation theory is developed for an arbitrary operator [Physical Formula] which can be expanded in power series of the perturbation parameter [Physical Formula]. A unified formulation allows the establishment of a formal interrelation between the methods of Rayleigh-Schrodinger, of Brillouin-Wigner and of canonical transformations. A new method, here called Born approximation, is proposed. |
