Analysis of injection operators in multigrid solvers for hybridized discontinuous Galerkin methods
Peipei Lu, Andreas Rupp, Guido Kanschat
Uniform convergence of the geometric multigrid V-cycle is proven for HDG methods with a new set of assumptions on the injection operators from coarser to finer meshes. The scheme i…

Homogeneous multigrid for embedded discontinuous Galerkin methods
Peipei Lu, Andreas Rupp, Guido Kanschat
We introduce a homogeneous multigrid method in the sense that it uses the same embedded discontinuous Galerkin (EDG) discretization scheme for Poisson's equation on all levels. In…
