For a generalized Stokes problem it is shown that weak solvability is equivalent to ellipticity of the system. In the case of ellipticity, the standard mixed finite element method converges if a Babuska-Brezzi condition for the pressure-form holds. This result is also true if the pressure operator i

We develop 2-grid schemes for solving nonlinear reaction-diffusion systems: where p = (p, q) is an unknown vector-valued function. The schemes use discretizations based on a mixed finite-element method. The 2-grid approach yields iterative procedures for solving the nonlinear discrete equations. Th
