    A stable class of improved second-derivative free Chebyshev-Halley type methods with optimal eighth order convergence 
    Cordero Barbero, Alicia; Kansal, Munish; Kanwar, Vinay; Torregrosa Sánchez, Juan Ramón (Springer-Verlag, 2016)
    [EN] In this paper, we present a uniparametric family of modified Chebyshev-Halley type methods with optimal eighth-order of convergence. In terms of computational cost, each member of the family requires only four functional ...

    Design of iterative methods with memory for solving nonlinear systems 
    Cordero Barbero, Alicia; Garrido-Saez, Neus; Torregrosa Sánchez, Juan Ramón; Triguero-Navarro, Paula (John Wiley & Sons, 2023-08)
    [EN] In this paper, we design two parametric classes of iterative methods without memory to solve nonlinear systems, whose convergence order is 4 and 7, respectively. From their error equations and to increase the convergence ...

    Memory in the iterative processes for nonlinear problems 
    Cordero Barbero, Alicia; Garrido-Saez, Neus; Torregrosa Sánchez, Juan Ramón; Triguero-Navarro, Paula (John Wiley & Sons, 2023-03-15)
    [EN] In this paper, we study different ways for introducing memory to a parametric family of optimal two-step iterative methods. We study the convergence and the stability, by means of real dynamics, of the methods obtained ...
