Abstract. In this paper a new discontinuous Galerkin method for the three dimensional electrostatic problem is presented. The divergence contraint is taken into account by a regularized variational formulation and the tangential and normal jumps of the discrete solution at the element interface are penalized. Optimal error estimates in a discrete energy norm are proved. Some numerical experiments confirm the theoretical predictions.
