Convergence and superconvergence of a nonconforming finite element method for the Stokes problem

In this paper, the four-parameter nonconforming finite element proposed in [30] and [19] is analyzed with the framework of Double Set Parameter (DSP) method, then it is applied to the stationary Stokes problem...
