Novel symplectic integrators for the Klein-Gordon equation with space- and time-dependent mass
Elsevier (2019-04)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 ... -
Symplectic propagators for the Kepler problem with time-dependent mass
Springer (2019-06)New numerical integrators specifically designed for solving the two-body gravitational problem with a time-varying mass are presented. They can be seen as a generalization of commutator-free quasi-Magnus exponential ...
