Ioannis K. Argyros, Santhosh George, Daya Ram Sahu Applicationes Mathematicae 47 (2020), 145-153 MSC: 65G99, 47H17, 49M15. DOI: 10.4064/am2352-1-2018 Published online: 7 June 2019


We extend the applicability of Newton’s method, so we can approximate a locally unique solution of a nonlinear equation in a Banach space setting in cases not covered before. To achieve this, we find a more precise set containing the Newton iterates than in earlier works.
