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

Novel symplectic integrators for the Klein-Gordon equation with space- and time-dependent mass [PDF]
, 2019 [EN] We consider the numerical time-integration of the non-stationary Klein-Gordon equation with position- and time-dependent mass. A novel class of time-averaged symplectic splitting methods involving double commutators is analyzed and 4th- and 6th ...

Explicit Time-Stepping for Stiff ODEs [PDF]
, 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]
, 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]
, 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.

Computing the structured pseudospectrum of a Toeplitz matrix and its extreme points
, 2012 The computation of the structured pseudospectral abscissa and radius (with respect to the Frobenius norm) of a Toeplitz matrix is discussed and two algorithms based on a low rank property to construct extremal perturbations are presented.
