Argyros, I.K.George, S.2020-03-312020-03-312017International Journal of Computing Science and Mathematics, 2017, Vol.8, 6, pp.495-505https://idr.nitk.ac.in/handle/123456789/11907This paper is devoted to the study of the seventh-order Steffensen-type methods for solving nonlinear equations in Banach spaces. Using the idea of a restricted convergence domain, we extended the applicability of the seventh-order Steffensen-type methods. Our convergence conditions are weaker than the conditions used in the earlier studies. Numerical examples are also given in this study. Copyright 2017 Inderscience Enterprises Ltd.Article
