摘要
Preconditioners for the saddle point systems arising from the discretization of elliptic problems by the local discontinuous Galerkin method are presented. They are based on multi-level methods for the interior penalty method. Performance results for Poisson and Stokes equations are presented. The methods are applied successfully to problems with advection.
