Variational Framework for Structure-Preserving Electromagnetic Particle-In-Cell Methods

Martin Campos Pinto, Katharina Kormann, Eric Sonnendrücker

In this article we apply a discrete action principle for the Vlasov--Maxwell equations in a structure-preserving particle-field discretization framework. In this framework the fini…
