A Higher Order Chebyshev-Halley-Type Family of Iterative Methods for Multiple Roots

Behl, Ramandeep; Martínez Molada, Eulalia; Cevallos-Alarcon, Fabricio Alfredo; Alarcon-Correa, Diego (MDPI AG, 2019-04)

[EN] The aim of this paper is to introduce new high order iterative methods for multiple roots of the nonlinear scalar equation; this is a demanding task in the area of computational mathematics and numerical analysis. ...
Diagnóstico del déficit de atención en niños mediante el análisis de la función ex-gaussiana

Cevallos Alarcón, Fabricio Alfredo (Universitat Politècnica de València, 2016-05-05)

[ES] El trastorno por déficit de atención con hiperactividad (TDAH), es una patología que se da con frecuencia en la edad infantil y la adolescencia y, continúa en algunos casos en la adultez, por lo tanto es un problema ...
Domain of existence for the solution of some IVP's and BVP's by using an efficient ninth-order iterative method

Cevallos, Fabricio; Hueso, José L.; Martínez Molada, Eulalia; Howk, Cory L. (John Wiley & Sons, 2020-09-30)

[EN] In this paper, we consider the problem of solving initial value problems and boundary value problems through the point of view of its continuous form. It is well known that in most cases these types of problems are ...
Local convergence balls for nonlinear problems with multiplicity and their extension to eight-order of convergence

Behl, Ramandeep; Martínez Molada, Eulalia; Cevallos-Alarcon, Fabricio Alfredo; Alshomrani, Ali Saleh (Hindawi Limited, 2019-01-02)

[EN] The main contribution of this study is to present a new optimal eighth-order scheme for locating zeros with multiplicity m > 1. An extensive convergence analysis is presented with the main theorem in order to demonstrate ...
Métodos iterativos para la resolución de problemas aplicados transformados a sistemas no lineales

Cevallos Alarcón, Fabricio Alfredo (Universitat Politècnica de València, 2023-05-22)

[ES] La resolución de ecuaciones y sistemas no lineales es un tema de gran interés teórico-práctico, pues muchos modelos matemáticos de la ciencia o de la industria se expresan mediante sistemas no lineales o ecuaciones ...
Semilocal Convergence for new Chebyshev-type iterative methods

Kumar, Abhimanyu; Gupta, D.K.; Martínez Molada, Eulalia; Hueso, José L.; Cevallos, Fabricio (R. Company, J. C. Cortés, L. Jódar and E. López-Navarro, 2019-07-12)

[EN] In this paper, the convergence of improved Chebyshev-Secant-type iterative methods are studied for solving nonlinear equations in Banach space settings. Its semilocal convergence is established using recurrence relations ...
