KW - Method of subspace corrections, preconditioning convergence rate of linear iterative
method.
AB - <p style="text-align: justify;">We discuss estimates for the rate of convergence of the method of successive
subspace corrections in terms of condition number estimate for the method of parallel
subspace corrections. We provide upper bounds and in a special case, a lower bound
for preconditioners defined via the method of successive subspace corrections.</p>
