SOLVING ODE’s NUMERICALLY WHILE PRESERVING ALL FIRST INTEGRALS
نویسندگان
چکیده
Using Discrete Gradient Methods (Quispel & Turner, J. Phys. A29 (1996) L341-L349) we construct integration methods that solve ordinary differential equations numerically while preserving all their first integrals (i.e. constants of the motion) exactly. 1 Department of Mathematics, La Trobe University, Bundoora, Melbourne, 3083, Australia. 2 E-mail: [email protected] 3 Instituut voor Theoretische Fysica, Universiteit van Amsterdam, Valckenierstraat 65, 1018XE, Amsterdam, The Netherlands.

Mean value theorem for integrals and its application on numerically solving of Fredholm integral equation of second kind with Toeplitz plus Hankel Kernel
The subject of this paper is the solution of the Fredholm integral equation with Toeplitz, Hankel and the Toeplitz plus Hankel kernel. The mean value theorem for integrals is applied and then extended for solving high dimensional problems and finally, some example and graph of error function are presented to show the ability and simplicity of the method.

متن کاملSolving Abel Integral Equations of First Kind via Fractional Calculus
We give a new method for numerically solving Abel integral equations of first kind. An estimation for the error is obtained. The method is based on approximations of fractional integrals and Caputo derivatives. Using trapezoidal rule and Computer Algebra System Maple, the exact and approximation values of three Abel integral equations are found, illustrating the effectiveness of the proposed ap...
متن کامل[SADE] a Maple package for the symmetry analysis of differential equations
We present the package SADE (Symmetry Analysis of Differential Equations) for the determination of symmetries and related properties of systems of differential equations. The main methods implemented are: Lie, non classical, Lie-Bäcklund and potential symmetries, invariant solutions, first-integrals, Nöther theorem for both discrete and continuous systems, solution of ordinary differential equa...
متن کاملDesign and Validation of a Numerical Problem Solving Environment for Ordinary Differential Equations
In the last decade, two distinct directions have emerged in the use of Ordinary Differential Equation (ODE) solver software (Enright ). These are Large Scale Scientific Computation on workstations or large mainframe computers and Problem Solving Environments (PSE’s) on personal computers. Most practicing engineers and scientists, as well as engineering and science students, use numerical softwa...
