On a secant-like method for solving generalized equations. (English) Zbl 1199.65182

Summary: S. Hilout and A. Piétrus [Positivity 10, No. 4, 693–700 (2006; Zbl 1118.47052)] had given a semilocal convergence analysis for a secant-like method to solve generalized equations using Hölder-type conditions introduced by the first author (for nonlinear equations). Here, we show that this convergence analysis can be refined under weaker hypothesis, and less computational cost. Moreover, finer error estimates on the distances involved and a larger radius of convergence are obtained.
