Abstract:

In this paper, it is shown that the upper and lower bounds of the errors in the Newton iterates recently obtained by Potra-Ptak and Miel, with the use of nondiscrete induction and majorizing sequence, respectively, follow immediately from the Kantorovich theorem and the Kantorovich recurrence relations. It is also shown that the upper and lower bounds of Miel are sharper than those of Potra-Ptak. Keywords Numerical analysis Potra-Ptaks bounds Miels bounds.
