Mixed Mortar Element Method forP1NC/P0 Element and Its Multigrid Method for the Incompressible Stokes Problem
We discuss a mortar-type P1NC/P0 element method for the incompressible Stokes problem. We prove the inf-sup condition and obtain the optimal error estimate. Meanwhile, we propose a 𝒲-cycle multigrid for solving this discrete problem and prove the optimal convergence of the multigrid method, that is,...
