A localized orthogonal decomposition strategy for hybrid discontinuous Galerkin methods

Peipei Lu, Roland Maier, Andreas Rupp

We formulate and analyze a multiscale method for an elliptic problem with an oscillatory coefficient based on a skeletal (hybrid) formulation. More precisely, we employ hybrid disc…

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…
