The group?s aim is to integrate, into a multidisciplinary group, the research carried out at the University in the fields of partial differential equations and other boundary problems in mathematical physics, cohomological and homotopical aspects of algebraic varieties, dynamic systems and astrodynamics, mathematical systems theory and its applications to the study of perturbations of linear systems, as well as the numerical modelling of all these topics.

    In this note we prove that an analytic symplectic action of a semisimple Lie algebra can be locally linearized in Darboux coordinates. This result yields simultaneous analytic linearization for Hamiltonian vector fields ...

    Artículo
    Acceso abierto
    L'espectacularitat de les galàxies barrades consisteix no solament en la presència de la barra, allargada en el centre de la galàxia, sinó també en els braços espirals o anells que es desenvolupen en les parts exteriors. ...
  • Action-angle variables and a KAM theorem for b-Poisson manifolds

    In this article we prove an action-angle theorem for b-integrable systems on b-Poisson manifolds improving the action-angle theorem contained in [LMV11] for general Poisson manifolds in this setting. As an application, we ...

    Structural stability ensures that the qualitative behavior of a system is preserved under small perturbations. We study it for planar bimodal linear dynamical systems, that is, systems consisting of two linear dynamics ...
