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…

Homogeneous multigrid method for HDG applied to the Stokes equation
Peipei Lu, Wei Wang, Guido Kanschat +1
We propose a multigrid method to solve the linear system of equations arising from a hybrid discontinuous Galerkin (in particular, a single face hybridizable, a hybrid Raviart--Tho…
