Argyros, I.K.George, S.2026-02-052018Matematicki Vesnik, 2018, 70, 1, pp. 1-11255165https://idr.nitk.ac.in/handle/123456789/25221We study third-order Newton-type methods free of bilinear operators for solving nonlinear equations in Banach spaces. Our convergence conditions are weaker than the conditions used in earlier studies. Numerical examples where earlier results cannot apply to solve equations but our results can apply are also given in this study. © 2018, Drustvo Matematicara Srbije.
