Abstract
FETI-DP method is developed for incompressible Stokes problem discretized by mortar-type C R (h) - P 0 (h) mixed elements. A preconditioner is proposed, and it is proved that the condition number of the preconditioned FETI-DP operator is bounded by (1 + log (H / h)) 2, where H and h are mesh sizes. Finally, the numerical tests are presented to verify the theoretical results.
