We consider algebraic multilevel preconditioning methods based on the recursive use of a 2 ร— 2 block incomplete factorization procedure in which the Schur complement is approximated by a coarse grid matrix. As is well known, for discrete second-order elliptic PDEs, optimal convergence properties are
