A class of efficient high-order iterative methods with memory for nonlinear equations and their dynamics

Howk, Cory L.; Hueso, J.L.; Martínez Molada, Eulalia; Teruel-Ferragud, Carles (John Wiley & Sons, 2018)

[EN] In this paper we obtain some theoretical results about iterative methods with memory for nonlinear equations. The class of algorithms we consider focus on incorporating memory without increasing the computational cost ...
Desenvolupament de nous mètodes per a la resolució d'equacions i sistemes d'equacions no lineals

Teruel Ferragud, Carles (Universitat Politècnica de València, 2016-01-11)

[EN] The necessity of solving nonlinear equations and systems arises naturally in the different areas of engineering and science when integral and differential equations are discretized. Nowadays, computers have become ...
Desenvolupament de nous mètodes per a la resolució d'equacions i sistemes d'equacions no lineals i Aplicacions

Teruel Ferragud, Carles (Universitat Politècnica de València, 2018-09-10)

La necesidad de resolver ecuaciones y sistemas de ecuaciones no lineales surge de manera natural en discretizar las ecuaciones integro-diferenciales que modelan los problemas de los que se encargan las diferentes ramas de ...
Determination of multiple roots of nonlinear equations and applications

Hueso Pagoaga, José Luís; Martínez Molada, Eulalia; Teruel Ferragud, Carles (Springer Verlag (Germany), 2015-03)

[EN] In this work we focus on the problem of approximating multiple roots of nonlinear equations. Multiple roots appear in some applications such as the compression of band-limited signals and the multipactor effect in ...
Dynamical study while searching equilibrium solutions in N-body problem

Budzko, Dzmitry; Hueso Pagoaga, José Luís; Martínez Molada, Eulalia; Teruel-Ferragud, Carles (Elsevier, 2016-05-01)

The theory of complex dynamics is usually applied to compare the global convergence properties of different iterative methods, by obtaining the attraction basins for simple polynomial equations in the complex domain. ...
Multipoint efficient iterative methods and the dynamics of Ostrowski's method

Hueso, Jose L.; Martínez Molada, Eulalia; Teruel-Ferragud, Carles (Taylor & Francis, 2019-09-02)

[EN] In this work, we introduce a modification into the technique, presented in A. Cordero, J.L. Hueso, E. Martinez, and J.R. Torregrosa [Increasing the convergence order of an iterative method for nonlinear systems, Appl. ...
Semilocal convergence of a k-step iterative process and its application for solving a special kind of conservative problems

Hernández-Verón, Miguel Angel; Martínez Molada, Eulalia; Teruel-Ferragud, Carles (Springer-Verlag, 2017)

[EN] In this paper, we analyze the semilocal convergence of k-steps Newton's method with frozen first derivative in Banach spaces. The method reaches order of convergence k + 1. By imposing only the assumption that the ...
