ETNA, Electron. Trans. Numer. Anal. 38, 1-16, electronic only (2011)


Summary: In this paper a parallel preconditioner for a FETI-DP formulation for a mortar discretization of a fourth order problem is presented and analyzed. We show that the condition number of the preconditioned FETI-DP operator is proportional to , where and are mesh sizes. $\textcent \?\sterling $??§?$\copyright \?\?\?\textcent $- ?? -- ??! ?" ? ?
