Dans cette note, nous proposons un procédé général pour construire des suites exactes autour d'un espace non conforme, et nous montrons comment ce procédé peut servir à écrire une loi de Gauss discrète convenable dans le cadre d'approximations Galerkin discontinues (DG) des équations de Maxwell temporelles en 2d.

In this note, we propose a general procedure to construct exact sequences involving a non-conforming function space and we show how this construction can be used to derive a proper discrete Gauss law for structure-preserving discontinuous Galerkin (DG) approximations to the time-dependent 2d Maxwell equations.
