Mixed hp-DGFEM for incompressible flows. (English) Zbl 1055.76032
An abstract framework is developed for several mixed discontinuous Galerkin (DG) approximations of Stokes problem. Within this framework, a priori error estimates for \(hp\)-approximations on tensor product meshes are derived, and a new stability estimate for discrete bilinear form is given.
