ab: Summary: The Newton scheme is used to construct an approximate inverse
    preconditioner for the Schur complement. However, this scheme is very
    expensive because of the computation cost of the matrix-matrix product.
    In this paper, the computation cost of the Newton scheme is reduced by
    implementing the preconditioner implicitly using the matrix-vector
    product. We also show that such an implementation is less expensive
    than computing the preconditioner explicitly.
