• Exponentially small splitting of separatrices in the perturbed McMillan map 

      Martín, Pau; Sauzin, D.; Martínez-Seara Alonso, M. Teresa (2011-10)
      Article
      Accés obert
      The McMillan map is a one-parameter family of integrable symplectic maps of the plane, for which the origin is a hyperbolic xed point with a homoclinic loop, with small Lyapunov exponent when the parameter is small. ...
    • Gevrey estimates for one dimensional parabolic invariant manifolds of non-hyperbolic fixed points 

      Baldomá Barraca, Inmaculada; Fontich, Ernest; Martín, Pau (2017-08-01)
      Article
      Accés obert
      We study the Gevrey character of a natural parameterization of one dimensional invariant manifolds associated to a parabolic direction of fixed points of analytic maps, that is, a direction associated with an eigenvalue ...

    • On the length and area spectrum of analytic convex domains 

      Martín, Pau; Ramírez Ros, Rafael; Tamarit Sariol, Anna (2016-01)
      Article
      Accés obert
      Area-preserving twist maps have at least two different (p, q)-periodic orbits and every (p, q)-periodic orbit has its (p, q)-periodic action for suitable couples (p, q). We establish an exponentially small upper bound for ...
    • Oscillatory motions for the restricted planar circular three body problem 

      Guàrdia Munarriz, Marcel; Martín, Pau; Martínez-Seara Alonso, M. Teresa (2016-02-01)
      Article
      Accés obert
      © 2015, Springer-Verlag Berlin Heidelberg. The restricted three body problem models the motion of a massless body under the influence of the Newtonian gravitational force caused by two other bodies called the primaries. ...
    • Oscillatory orbits in the restricted elliptic planar three body problem 

      Guàrdia Munarriz, Marcel; Martín, Pau; Sabbagh, Lara; Martínez-Seara Alonso, M. Teresa (Southwest Missouri State University, 2017-01-01)
      Article
      Accés obert
      The restricted planar elliptic three body problem models the motion of a massless body under the Newtonian gravitational force of two other bodies, the primaries, which evolve in Keplerian ellipses. A trajectory is called ...
    • Resurgence of inner solutions for perturbations of the McMillan map 

      Martín, Pau; Sauzin, D.; Martínez-Seara Alonso, M. Teresa (2011-09)
      Article
      Accés obert
      Abstract. A sequence of \inner equations" attached to certain perturbations of the McMillan map was considered in [5], their solutions were used in that article to measure an exponentially small separatrix splitting. We ...
