A new tool to study real dynamics: The convergence plane
Magreñán, Á. Alberto (UNIR)
Tipo de Ítem:Articulo Revista Indexada
In this paper, the author presents a graphical tool that allows to study the real dynamics of iterative methods whose iterations depends on one parameter in an easy and compact way. This tool gives the information as previous tools such as Feigenbaum diagrams and Lyapunov exponents for every initial point. The convergence plane can be used, inter alia, to find the elements of a family that have good convergence properties, to see how the basins of attraction changes along the elements of the family, to study two-point methods such as Secant method or even to study two-parameter families of iterative methods. To show the applicability of the tool an example of the dynamics of the Damped Newton's method applied to a cubic polynomial is presented in this paper. (C) 2014 Elsevier Inc. All rights reserved.

Decision model for siting transport and logistic facilities in urban environments: A methodological approach Frailea, Alberto; Larrodé, Emilio; Magreñán, Á. Alberto (UNIR); Sicilia, Juan Antonio (UNIR) (Journal of Computational and Applied Mathematics, 01/2016)In this study, based on the use of a geographic information system (GIS), we define a decision model for determining the possible optimal locations of various facilities in an urban setting, which can be used by the transport ...

Argyros, Ioannis K; Magreñán, Á. Alberto (UNIR); Orcos, Lara (UNIR); Sicilia, Juan Antonio (UNIR) (Journal of Mathematical Chemistry, 08/2017)We present a local convergence analysis for a relaxed two-step Newton-like method. We use this method to approximate a solution of a nonlinear equation in a Banach space setting. Hypotheses on the first Fr,chet derivative ...
