Geometric Numerical Integration of Differential Equations

Geometric Numerical Integration of Differential Equations

What is geometric integration? ‘Geometric integration’ is the term used to describe numerical methods for computing the solution of differential equations, while preserving one or more physical/mathematical properties of the system exactly (i.e. up to round–off error)1. What properties can be preserved in this way? A first aspect of a dynamical system that is important to preserve is its phase ...

The numerical integration of ordinary differential equations

A reliable efficient general-purpose method for automatic digital computer integration of systems of ordinary differential equations is described. The method operates with the current values of the higher derivatives of a polynomial approximating the solution. It is thoroughly stable under all circumstances, incorporates automatic starting and automatic choice and revision of elementary interva...

Local Linearization Method for Numerical Integration of Delay Differential Equations

In this paper, a new approach for the numerical computation of Delay Differential Equations (DDEs) is introduced. The essential idea consists on obtaining numerical integrators that use a code expressly developed for linear DDEs, in contrast with the conventional approach of using a code for ordinary differential equations. Specifically, two numerical schemes of such new class of integrators ar...
