摘要：
We consider several mixed discontinuous Galerkin approximations of the Stokes problem and propose an abstract framework for their analysis. Using this framework, we derive a priori error estimates for hp-approximations on tenser product meshes. We also prove a new stability estimate for the discrete divergence bilinear form.
