Compositions of pseudo-symmetric integrators with complex coefficients for the numerical integration of differential equations
Fernando Casas, Philippe Chartier, Alejandro Escorihuela-Tomas +1
In this paper, we are concerned with the construction and analysis of a new class of methods obtained as double jump compositions with complex coefficients and projection on the re…
Uniformly accurate numerical schemes for a class of dissipative systems
Philippe Chartier, Mohammed Lemou, Léopold Trémant
We consider a class of relaxation problems mixing slow and fast variations which can describe population dynamics models or hyperbolic systems, with varying stiffness (from non-sti…
Global time-renormalization of the gravitational -body problem
M. Antoñana, P. Chartier, J. Makazaga +1
This work considers the {\em gravitational} -body problem and introduces global time-renormalization {\em functions} that allow the efficient numerical integration with fixed ti…
