Abstract
We consider a class of approximations by rectangular finite elements f or the Stokes problem, with polynomial pressure approximation of degre e at most k - 1 on each rectangle. We will build an optimal velocity a pproximation (when both computational cost and accuracy are considered ), in order to obtain stable elements.
