Abstract
Purpose: The present paper is aimed at estimating of accuracy and justification the application effectiveness of the multi-step differential transform method for solving non-linear boundary value problems. Methods: This article reviews the multi-step differential transform method for solving non-linear boundary value problem. Results: The upper bound of estimate of accuracy of approximate solutions of non-linear boundary value problems by the multi-step differential transform method for the case of accounting of restricted quantity of discretes of differential spectra is offered. We present results of numerical solution of a non-linear boundary value problem and shown the efficiency of application of the multi-step differential transform method compared with traditional differential transform method. Discussion: It is shown, that upper bound of error estimate of the multi-step differential transform method compared with traditional differential transform method is decreased in s p time, where s is the quantity of accounted discretes, p is the quantity of intervals, over which the given time interval is divided. The multi-step differential transform method gives the principal possibility to get more exact value of random analytic function ) (tx on the end of interval at restricted quantity of discretes of differential spectrum compared with the differential transform method application.
