## Abstract Polikanov's perturbation method for the solution of the radial SchrΓΆdinger equation is shown to be equivalent to the usual RayleighβSchrΓΆdinger method but with __full__ normalization instead of __intermediate__ noralization. The energy corrections are shown to be the same to all orders.
Two perturbation methods for nonlinear autonomous discrete-time dynamical systems are presented. They generalize the classical Lindstedt-Poincar6 and multiple scale perturbation methods that are valid for continuous-time systems. The Lindstedt-Poincar6 method allows determination of the periodic or
