Abstract
In this paper we describe a computation of iterative operator-splitting method, which are known as competitive splitting methods, see \cite{geiser_09_1} and \cite{geiser_08_1}. We derived a closed form, based on commutators for the iterative method. The schemes apply extrapolation schemes and Pade approximations to the exp-functions. The error analysis describe the approximation errors. Numerical examples of ordinary and partial differential equations support the fast computation ideas.
