    • A note on the periodic orbits and topological entropy of graph maps 

      Alseda Soler, Lluís; Juher, D.; Mumbrú i Rodriguez, Pere (2000)
      Article
      Accés obert
      This paper deals with the relationship between the periodic orbits of continuous maps on graphs and the topological entropy of the map. We show that the topological entropy of a graph map can be approximated by the entropy ...

    • An analytical approach to codimension-2 sliding bifurcations in the dry friction oscillator 

      Martínez-Seara Alonso, M. Teresa; Guàrdia Munarriz, Marcel; Hogan, S. John (2010)
      Article
      Accés restringit per política de l'editorial
      In this paper, we analytically consider sliding bifurcations of periodic orbits in the dry-friction oscillator. The system depends on two parameters: F, which corresponds to the intensity of the friction, and ω, the ...

    • Bifurcation gaps in asymmetric and high-dimensional hypercycles 

      Puig, Júlia; Farre, Gerard; Guillamon Grabolosa, Antoni; Fontich Julia, Ernest; Sardanyes, Josep (2018-01-01)
      Article
      Accés obert
      Hypercycles are catalytic systems with cyclic architecture. These systems have been suggested to play a key role in the maintenance and increase of information in prebiotic replicators. It is known that for a large enough ...

    • Continuation of bifurcations of periodic orbits for large-scale systems 

      Net Marcé, Marta; Sánchez Umbría, Juan (2015-01-01)
      Article
      Accés obert
      A methodology to track bifurcations of periodic orbits in large-scale dissipative systems depending on two parameters is presented. It is based on the application of iterative Newton-Krylov techniques to extended systems. ...

    • Effective Stability Around Periodic Orbits of the Spatial RTBP 

      Jorba, Angel; Villanueva Castelltort, Jordi (1995)
      Article
      Accés obert
      In this work we study the dynamics around an elliptic periodic orbit of Hamiltonian systems. To this end we have developped an algorithm to compute a normal form (up to a finite order) around this orbit, that gives an ...

    • HAmsys 2014 

      Ollé Torner, Mercè; Barrabés Vera, Esther; Gómez Muntané, Gerard; Mondelo González, José María (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 ...

    • Horseshoe periodic orbits in the restricted three body problem 

      Llibre Saló, Jaume; Ollé Torner, Mercè (2001)
      Article
      Accés obert

    • Invariant manifolds of L_3 and horseshoe motion in the restricted three-body problem 

      Barrabés Vera, Esther; Ollé Torner, Mercè (2005)
      Article
      Accés obert
      In this paper, we consider horseshoe motion in the planar restricted three-body problem. On one hand, we deal with the families of horseshoe periodic orbits (which surround three equilibrium points called L3, L4 and L5), ...

    • J2 effect and elliptic inclined periodic orbits in the collision three-body problem 

      Barrabés Vera, Esther; Cors Iglesias, Josep Maria; Pinyol Pérez, Conxita; Soler Villanueva, Jaume (2008-01)
      Article
      Accés obert
      The existence of a new class of inclined periodic orbits of the collision restricted three{body problem is shown. The symmetric periodic solutions found are perturbations of elliptic kepler orbits and they exist only for ...

    • Motion close to the hopf bifurcation of the vertical family of periodic orbits of L^4 

      Ollé Torner, Mercè; Pacha Andújar, Juan Ramón; Villanueva Castelltort, Jordi (2003)
      Article
      Accés obert
      The paper deals with different kinds of invariant motions (periodic orbits, 2D and 3D invariant tori and invariant manifolds of periodic orbits) in order to analyze the Hamiltonian direct Hopf bifurcation that takes place ...

    • On the length spectrum of analytic convex billiard tables 

      Tamarit Sariol, Anna (Universitat Politècnica de Catalunya, 2011)
      Projecte Final de Màster Oficial
      Accés obert
      Billiard maps are a type of area-preserving twist maps and, thus, they inherit a vast num-ber of properties from them, such as the Lagrangian formulation, the study of rotational invariant curves, the types of periodic ...

    • Periodic orbits of horseshoe type in the planar restricted three-body problem 

      Llibre Saló, Jaume; Ollé Torner, Mercè (2002)
      Article

    • Stability and asymptotic behaviour of the vertical family of periodic orbits around L_5 of the restricted three-body problem 

      Jorba, Angel; Villanueva Castelltort, Jordi (1997)
      Article
      Accés obert
      In this work we study some numerical results about a family of periodic orbits of the Restricted Three Body Problem (RTBP). The family considered is one of the Lyapunov families related to the equlibrium point $L_5$. More ...

    • The frequency map for billiards inside ellipsoids 

      Ramírez Ros, Rafael; Sánchez Casas, José Pablo (2010-04)
      Report de recerca
      Accés obert
      The billiard motion inside an ellipsoid Q Rn+1 is completely integrable. Its phase space is a symplectic manifold of dimension 2n, which is mostly foliated with Liouville tori of dimension n. The motion on each Liouville ...

    • Warp evidence in precessing galactic bar models 

      Sanchez Martin, P; Romero Gómez, Mercè; Masdemont Soler, Josep (EDP Sciences, 2016-04-01)
      Article
      Accés obert
      Most galaxies have a warped shape when they are seen edge-on. The reason for this curious form is not completely known so far, so in this work we apply dynamical system tools to contribute to its explanation. Starting from ...
