dc.description.abstract	Chatelin has established, under assumptions on the unknown invariant subspace, the quadratic convergence of Newton's iterative refinements. We modify the procedure in line with Demmel's suggestions and obtain a criterion for quadratic convergence in terms of the known initial approximation. Our procedure enables computable error estimates to be obtained for the iterations.
