Dynamical behavior of asteroids near resonance: the 4:1 gap and the 7:2 group
Grau Sánchez, Miguel; González Casado, Guillermo (1999-08)
Article
Accés restringit per política de l'editorialA comparative study of the evolution of the Sun–Jupiter–Asteroid system near the 4:1 and 7:2 resonances is performed by means of two techniques that proceed differently from the Hamiltonian corresponding to the planar ... -

Note on the efficiency of some iterative methods for solving nonlinear equations
Grau Sánchez, Miguel; Noguera Batlle, Miquel; Díaz Barrero, José Luis (2015-11-02)
Article
Accés obertThe e ciency of algorithms for solving nonlinear equations is a measure of comparison between di erent iterative methods. In the case of scalar equations two parameters are considered as it is well-known, but frequently ... -
On a Moser-Steffensen type method for nonlinear systems of equations
Amat Plata, Sergio; Grau Sánchez, Miguel; Hernández Verón, Miguel Angel; Rubio, María Jesús (2016-12)
Article
Accés obertThis paper is devoted to the construction and analysis of a Moser–Steffensen iterative scheme. The method has quadratic convergence without evaluating any derivative nor inverse operator. We present a complete study of the ... -
On computational order of convergence of some multi-precision solvers of nonlinear systems of equations
Grau Sánchez, Miguel; Grau Gotés, Maria Àngela; Díaz Barrero, José Luis (2011-05-02)
Report de recerca
Accés obertIn this paper the local order of convergence used in iterative methods to solve nonlinear systems of equations is revisited, where shorter alternative analytic proofs of the order based on developments of multilineal ...
