Resumen de A new convergence analysis for the two-step Newton Method for order three

Ioannis K. Argyros, Sanjay K. Khattri

• We present a tighter than before semilocal convergence analysis for the two-step Newton method of order three using recurrent functions.Numerical examples are also provided to show that our convergence criteria are satisfied but earlier studies such as in nine, thirteen, fifteen are not satisfied.
