Optimal selection of the bubble function in the stabilization of the P1- P1 element for the Stokes problem. (English) Zbl 0833.76037

Summary: We propose a criterion for the selection of the local stabilizing function of the mini-discretization of the Stokes problem. We then show how the application of this criterion to nonconforming approximation leads to a particularly simple solution.
