Local generic behavior of a planar Filippov system with non-smooth switching curve
Fernandes Larrosa, Juliana; Martínez-Seara Alonso, M. Teresa; Teixeira, Marco Antonio (Springer Nature, 2021-10-18)
Article
Accés obertThis paper discusses the generic local classification of typical singularities of 2D piecewise smooth vector fields when the switching set is an non smooth curve. The main goal is to obtain classification results concerning ... -
Lower and upper bounds for the splitting of separatrices of the pendulum under a fast quasiperiodic forcing
Delshams Valdés, Amadeu; Gelfreich, Vassili; Jorba, Angel; Martínez-Seara Alonso, M. Teresa (1997)
Article
Accés obertQuasiperiodic perturbations with two frequencies $(1/\varepsilon ,\gamma /\varepsilon )$ of a pendulum are considered, where $\gamma $ is the golden mean number. We study the splitting of the three-dimensional invariant ... -
On the asymptotic wavenumber of spiral waves in lambda - omega systems
Aguareles Carrero, María; Baldomá Barraca, Inmaculada; Martínez-Seara Alonso, M. Teresa (2016-01-01)
Article
Accés obertIn this paper we consider spiral wave solutions of a general class of $\lambda -\omega $ systems with a small twist parameter q and we prove that the asymptotic wavenumber of the spirals is a ${{\mathcal{C}}^{\infty}}$ ... -
On the numerical computation of Diophantine rotation numbers of analytic circle maps
Martínez-Seara Alonso, M. Teresa; Villanueva Castelltort, Jordi (2004)
Article
Accés obertIn this paper we present a numerical method to compute Diophantine rotation numbers of circle maps with high accuracy. We mainly focus on analytic circle diffeomorphisms, but the method also works in the case of (enough) ... -
Orbits of unbounded energy in quasi-periodic perturbations of geodesic flows
Delshams Valdés, Amadeu; Llave Canosa, Rafael de la; Martínez-Seara Alonso, M. Teresa (2003)
Article
Accés obertWe show that certain mechanical systems, including a geodesic °ow in any dimension plus a quasi-periodic perturbation by a potential, have orbits of unbounded energy. The assumptions we make in the case of geodesic °ows ... -
Oscillatory motions and parabolic manifolds at infinity in the planar circular restricted three body problem
Capinski, Maciej J.; Guàrdia Munarriz, Marcel; Martínez-Seara Alonso, M. Teresa; Zgliczynski, Piotr; Martín de la Torre, Pablo (Elsevier, 2022-05-25)
Article
Accés obertConsider the Restricted Planar Circular 3 Body Problem. If the trajectory of the body of zero mass is defined for all time, it can have the following four types of asymptotic motion when time tends to infinity forward or ... -
