Pseudospectral reduction to compute Lyapunov exponents of delay differential equations [PDF]

open access: yes, 2018
A recent pseudospectral collocation is used to reduce a nonlinear delay differential equation to a system of ordinary differential equations. Standard methods are then applied to compute Lyapunov exponents.

The Asymptotic Iteration Method Revisited

open access: yes, 2020
The Asymptotic Iteration Method (AIM) is a technique for solving analytically and approximately the linear second-order differential equation, especially the eigenvalue problems that frequently appear in theoretical and mathematical physics. The analysis

Symplectic integrators for second-order linear non-autonomous equations [PDF]

open access: yes, 2017
[EN] Two families of symplectic methods specially designed for second-order time-dependent linear systems are presented. Both are obtained from the Magnus expansion of the corresponding first-order equation, but otherwise they differ in significant ...

Explicit Time-Stepping for Stiff ODEs [PDF]

open access: yes, 2003
We present a new strategy for solving stiff ODEs with explicit methods. By adaptively taking a small number of stabilizing small explicit time steps when necessary, a stiff ODE system can be stabilized enough to allow for time steps much larger than what

Reducibility and contractivity of Runge-Kutta methods revisited [PDF]

open access: yes, 2018
The exact relation between a Cooper-like reducibility concept and the reducibilities introduced by Hundsdorfer, Spijker and by Dahlquist and Jeltsch is given.

An Analytical Technique for Solving Nonlinear Heat Transfer Equations [PDF]

open access: yes, 2010
In this paper, an analytic technique, namely the New Homotopy Perturbation Method (NHPM) is applied for solving the nonlinear differential equations arising in the field of heat transfer.
