Аннотация: A class (m,k)-methods is discussed for the numerical solution of the initial value problems for implicit systems of ordinary differential equations. The order conditions and convergence of the numerical solution in the case of implementation of the scheme with the time-lagging of matrices derivatives for systems of index 1 are obtained. At k ? 4 the order conditions are studied and schemes optimal computing costs are obtained. © Springer International Publishing Switzerland 2015.

Аннотация: The Cauchy problem for a stiff system of ODEs unresolved with respect to the derivative often arises in chemical kinetics, mechanical engineering, and other important applications. The two-stage L-stable Rosenbrock-type method is derived. An integration algorithm of alternating stepsize is designed based on the method, aimed at solving implicit stiff systems of ODEs. Numerical results confirming the efficiency of the new algorithm are given.
В химической кинетике, машиностроении и в других важных приложениях возникает задача Коши для жесткой системы ОДУ неразрешенных относительно производной. Построен двухстадийный L-устойчивый метод типа Розенброка, предназначенный для решения неявных жестких систем ОДУ. На основе этого метода сформулирован алгоритм интегрирования переменного шага. Приведены результаты расчетов, подтверждающие эффективность нового алгоритма.

Аннотация: The Cauchy problem for stiff systems of ODEs unresolved with respect to derivative arises in electrical engineering, chemical kinetics and other important areas. Authors derived an L-stable (5, 3)-method for solving the first index systems of DAEs. An algorithm of the alternating integration stepsize based on this method is formulated. The algorithm allows freezing the Jacobian matrix of the system to be solved. Numerical results confirming the efficiency of the new algorithm are given. © 2018 IEEE.

Аннотация: ABSTRACT: A form of Rosenbrock-type methods optimal in terms of the number ofnon-zero parameters and computational costs per step is considered. Atechnique of obtaining (m, k) -methodsfrom some well-known Rosenbrock-type methods is justified. Formulas fortransforming the parameters of (m, k) -schemesand for obtaining a stability function are given for two canonicalrepresentations of the schemes. An L-stable(3 , 2) -methodof order 3 is proposed, which requires two evaluations of the function:one evaluation of the Jacobian matrix and oneLU-decompositionper step. A variable step size integration algorithm based on the(3 , 2) -methodis formulated. It provides a numerical solution for both explicit andimplicit systems of ODEs. Numerical results are presented to show theefficiency of the new algorithm. © 2020, Pleiades Publishing, Ltd.
