Resumen de Local convergence for multi-point-parametric Chebyshev–Halley-type methods of high convergence order

Ioannis K. Argyros, Santhosh George, Ángel Alberto Magreñán Ruiz

• We present a local convergence analysis for general multi-point-Chebyshev–Halley-type methods (MMCHTM) of high convergence order in order to approximate a solution of an equation in a Banach space setting. MMCHTM includes earlier methods given by others as special cases. The convergence ball for a class of MMCHTM methods is obtained under weaker hypotheses than before. Numerical examples are also presented in this study.
