Rates of robust superlinear convergence of preconditioned Krylov methods for elliptic FEM problems

This paper considers the iterative solution of finite element discretizations of second-order elliptic boundary value problems. Mesh independent estimations are given for the rate of superlinear convergence of preconditioned Krylov methods, involving the connection between the convergence rate and t...
