    Indudablemente uno de los legados más importantes de Hamilton es la rama de la teoría de ecuaciones diferenciales que en honor a su nombre se denomina Sistemas Hamiltonianos. Ejemplos de sistemas Hamiltonianos son la ...
  • Hamilton-Jacobi theory and the evolution operator 

    Cariñena, José F.; Gràcia Sabaté, Francesc Xavier; Martínez, Eduardo; Marmo, Giuseppe; Muñoz Lecanda, Miguel Carlos; Román Roy, Narciso (Prensas Univ. Zaragoza, 2009-04)
    Part of book or chapter of book

    The geometric framework for the Hamilton-Jacobi theory developed in [14, 17, 39] is extended for multisymplectic first-order classical field theories. The Hamilton-Jacobi problema is stated for the Lagrangian and the ...
  • Hamiltonian methods in stability and bifurcations problems for artificial satellite dynamics 

    Teixidó Roman, Miguel (Universitat Politècnica de Catalunya, 2011-03)
    Master thesis
    Open Access
    The dynamics of a rigid body in a central gravitational eld can be modelled by a Hamiltonian system with continuous symmetries implemented by an action of the group SO(3). Depending on the particular geometry of the body ...
  • Hamiltonian Systems in Multisymplectic Field Theories 

    Echeverría Enríquez, Arturo; León, Manuel de; Muñoz Lecanda, Miguel Carlos; Román Roy, Narciso (2005-06-20)
    Article
    Open Access
    We consider Hamiltonian systems in first-order multisymplectic field theories. First we review the construction and properties of Hamiltonian systems in the so-called restricted multimomentum bundle using Hamiltonian ...
  • Hamiltonian systems with orbits covering densely submanifolds of small codimension 

    Fontich i Julià, Ernest; Martín de la Torre, Pablo (2000)
    Article
    Open Access
    The existence of a transition chain in a Hamiltonian system leads to the existence of orbits shadowing it, if some lambda lemma can be applied. This fact has been used to prove the existence of diffusion in perturbations ...

    In this talk we give an explanation of transport in the solar system based in dynamical systems theory. More concretely we consider (as a first approximation) different bicircular problems (i.e. Sun, Jupiter, a planet ...

  • Handling exceptions in logic programming without negation as failure 

    Confalonieri, Roberto; Prade, Henri; Nieves Sánchez, Juan Carlos (Springer, 2011)
    Conference report
    Restricted access - publisher's policy
    Default rules, i.e. statements of the form normally a’s are b’s, are usually handled in Answer Set Programming by means of negation as failure which provides a way to capture exceptions to normal situations. In this paper ...
  • Handling high parameter dimensionality in reinforcement learning with dynamic motor primitives 

    Colomé Figueras, Adrià; Alenyà Ribas, Guillem; Torras, Carme (2013)
    Conference report
    Open Access
    Dynamic Motor Primitives (DMP) are nowadays widely used as movement parametrization for learning trajectories, because of their linearity in the parameters, rescalation robustness and continuity. However, when learning a ...
