Ben Belgacem, Faker The mixed mortar finite element method for the incompressible Stokes problem: Convergence analysis. (English) Zbl 0959.65126 SIAM J. Numer. Anal. 37, No. 4, 1085-1100 (2000). 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.
