Abstract. In this paper, we use Newton's method to approximate a locally unique solution of an equation in Banach spaces and introduce recurrent functions to provide a weaker semilocal convergence analysis for Newton's method than before [1]- [13], in some interesting cases, provided that the Fréchet-derivative of the operator involved is p-Hölder continuous (p ∈ (0, 1]). Numerical examples involving two boundary value problems are also provided.
