    • Rotation sets for orbits of degree one circle maps 

      Alseda Soler, Lluís; Chas, Moira; Mañosas Capellades, Francesc (2000)
      Article
      Open Access
      Let F be the lifting of a circle map of degree one. In [R. Bam´on, I. P. Malta, M. J. Pacifico and F.Takens, Ergodic Theory Dyn. Syst. 4, 493-498 (1984; Zbl 0605.58027)], a notion of F-rotation interval of a point x 2 ...
    • The period function for Hamiltonian systems with homogeneous nonlinearities 

      Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor; Mañosas Capellades, Francesc (1996)
      Article
      Open Access
      The paper deals with Hamiltonian systems with homogeneous nonlinearities. We prove that such systems have no isochronous centers, that the period annulus of any of its centres is either bounded or the whole plane and that ...
    • Types d'orbites et dynamique minimale pour les applicationes continues de graphes 

      Alseda Soler, Lluís; Gauteuro, François; Guaschi, J.; Los, J.; Mañosas Capellades, Francesc; Mumbrú i Rodriguez, Pere (2001)
      Article
      Open Access
      We define the type of a periodic orbit of a graph map. We consider the class of ‘train-track’ representatives, that is, those graph maps which minimize the topological entropy of the topological representatives of a given ...
