The mixed mortar finite element method for the incompressible Stokes problem: Convergence analysis. (English) Zbl 0959.65126
The author justifies the global inf-sup condition for a wide class of domain decompositions with respect to mortar technique applied to Stokes equations. The proof is based on the algebraic properties of the connectivity matrix.
