Se desarrolla la teoría de perturbaciones independientes del tiempo para un operador arbitrario [Fórmula física] que se puede expandir en series de potencias de un parámetro de perturbación [Fórmula física]. Una formulación unificada permite establecer la interrelación formal entre los métodos de Rayleigh-Schrodinger, Brillouin-Wigner y el de transformaciones canónicas. Se propone un nuevo método que hemos denominado aproximación de Born.
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.
