Order of convergence of evolution operator method

Abstract

In this paper the order of convergence of the evolution operator method used to solve a nonlinear autonomous system in ODE's [2] is investigated. The order is found, to be 2N+1 where N comes from the [N+1,N] Pade approximation used in the method. The order is independent of the choice of the weight function.
