Argyros, I.K.George, S.2020-03-312020-03-312017Nonlinear Functional Analysis and Applications, 2017, Vol.22, 1, pp.41-58https://idr.nitk.ac.in/handle/123456789/11552We present a new convergence analysis for the Kurchatov method using our new idea of restricted convergence domains in order to solve nonlinear equations in a Banach space setting. The suffcient convergence conditions are weaker than in earlier studies. Hence, we extend the applicability of this method. Moreover, our radius of convergence is larger leading to a wider choice of initial guesses and fewer iterations to achieve a desired error tolerance. Numerical examples are also provided showing the advantages of our approach over earlier work. 2017 Kyungnam University Press.Article
