We consider applying the preconditioned conjugate gradient (PCG) method to solving linear systems Ax = b where the matrix A comes from the discretization of second-order elliptic operators with Dirichlet boundary conditions. Let (L+ ) -1 (L t + ) denote the block Cholesky factorization of A with low

## Abstract Here we present and analyze a NeumannβNeumann algorithm for the mortar finite element discretization of elliptic fourthβorder problems with discontinuous coefficients. The fully parallel algorithm is analyzed using the abstract Schwarz framework, proving a convergence which is independe
