In this paper we construct Discontinuous Galerkin approximations of the Stokes problem where the velocity field is -conforming. This implies that the velocity solution is divergence-free in the whole domain. This property can be exploited to design a simple and effective preconditioner for the final linear system.

Abstract
In this paper we construct Discontinuous Galerkin approximations of the Stokes problem where the velocity field is -conforming. This implies that the velocity solution is divergence-free in the whole domain. This property can be exploited to design a simple and effective preconditioner for the final linear system.File in questo prodotto:
