Abstract

The mixed finite element scheme of the Stokes problem withpressure stabilization is analyzed for the cross-grid Pk−Pk−1elements, k≥1, using discontinuous pressures. The Pk+−Pk−1 elements are also analyzed. We prove the stability of the scheme using themacroelement technique. The order of convergence follows from the standardtheory of mixed methods. The macroelement technique can also be applicableto the stability analysis for some higher order methods using continuouspressures such as Taylor-Hood methods, cross-grid methods, or iso-gridmethods.
