Variational integrators and time-dependent lagrangian systems
M. de Leon, D. Martin de Diego
Abstract
This paper presents a method to construct variational integrators for time-dependent lagrangian systems. The resulting algorithms are symplectic, preserve the momentum map associated with a Lie group of symmetries and also describe the energy variation.
