La seva activitat de recerca està dirigida al desenvolupament de mètodes analítics i numèrics per sistemes dinàmics, gaudint de lideratge científic en diversos temes, com Integrabilitat, Objectes invariants, Teoria K.A.M., Camps vectorials plans i aplicacions a neurociència, Mètode de Poincaré-Melnikov, Escissió exponencialment petita de separatrius, Difusió, Mecànica Celest i Astrodinàmica.
La qualitat d'aquesta activitat es reflecteix tant en la qualitat i quantitat de publicacions, algunes d'elles en col.laboració amb grups internacionals de primera línia, com en la gestió científica desenvolupada, plasmada en l'organització de múltiples events (congressos i jornades , programes de recerca, xarxes temàtiques, etc.), la participació en diversos comitès editorials de revistes de prestigi reconegut, així com en una àmplia formació doctoral.

  • Arnold diffusion for a complete family of perturbations 

    Delshams Valdés, Amadeu; Gonçalves Schaefer, Rodrigo (Springer, 2017-01-01)
    Article
    Accés obert
    In this work we illustrate the Arnold diffusion in a concrete example — the a priori unstable Hamiltonian system of 2 + 1/2 degrees of freedom H(p, q, I, f, s) = p2/2+ cos q - 1 + I2/2 + h(q, f, s; e) — proving that for ...
  • A unified approach to explain contrary effects of hysteresis and smoothing in nonsmooth systems 

    Bonet Revés, Carles; Martínez-Seara Alonso, M. Teresa; Fossas Colet, Enric; Jeffrey, Mike R. (2017-09-01)
    Article
    Accés restringit per política de l'editorial
    Piecewise smooth dynamical systems make use of discontinuities to model switching between regions of smooth evolution. This introduces an ambiguity in prescribing dynamics at the discontinuity: should the dynamics be given ...
  • Central configurations of the planar coorbial satellite problem 

    Cors Iglesias, Josep Maria; Llibre Saló, Jaume; Ollé Torner, Mercè (2004-10)
    Article
    Accés obert
    We study the planar central configurations of the 1 +n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2=n=4. Numerically, ...
  • Phasic firing and coincidence detection by subthreshold negative feedback: divisive or subtractive or, better, both 

    Huguet Casades, Gemma; Meng, Xiangying; Rinzel, John (2017-02-02)
    Article
    Accés obert
    Phasic neurons typically fire only for a fast-rising input, say at the onset of a step current, but not for steady or slow inputs, a property associated with type III excitability. Phasic neurons can show extraordinary ...
  • On the length and area spectrum of analytic convex domains 

    Martín, Pau; Ramírez Ros, Rafael; Tamarit Sariol, A. (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 ...
  • Solar radiation pressure assisted transfers between Lissajous orbits of the Sun-Earth system 

    Stefania, Soldini; Gomez Muntané, Gerard; Masdemont Soler, Josep; Camilla, Colombo; Walker, Scott (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This article investigates a propellant-free transfer between Lissa jous orbits in the Sun-Earth system modelled as a photo-gravitational circular restricted three body p roblem. The geometry of the phase space around the ...
  • On the asymptotic wavenumber of spiral waves in lambda - omega systems 

    Aguareles Carrero, Maria; Baldomá Barraca, Inmaculada; Martínez-Seara Alonso, M. Teresa (2016-01-01)
    Article
    Accés restringit per política de l'editorial
    In this paper we consider spiral wave solutions of a general class of $\lambda -\omega $ systems with a small twist parameter q and we prove that the asymptotic wavenumber of the spirals is a ${{\mathcal{C}}^{\infty}}$ ...
  • On bifurcations of homoclinic tangencies in area-preserving maps on non-orientable manifolds 

    Delshams Valdés, Amadeu; Gonchenko, Marina; Gonchenko, Sergey (Springer, 2016)
    Capítol de llibre
    Accés restringit per política de l'editorial
    We study bifurcations of non-orientable area-preserving maps with quadratic homoclinic tangencies. We study the case when the maps are given on non-orientable two-dimensional manifolds. We consider one and two parameter ...
  • Dynamics in the centre manifold around equilibrium points in periodically perturbed three-body problems 

    Le Bihan, Bastien; Masdemont Soler, Josep; Gomez Muntané, Gerard; Lizy-Destrez, Stephanie (2016)
    Text en actes de congrés
    Accés obert
    A new application of the parameterization method is pre- sented to compute invariant manifolds about the equilib- rium points of Periodically Perturbed Three-Body Problems ( PPTBP ). These techniques are applied to obtain ...
  • Arnold's mechanism of diffusion in the spatial circular restricted three-body problem: A semi-analytical argument 

    Delshams Valdés, Amadeu; Gidea, Marian; Roldán, Pablo (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    We consider the spatial circular restricted three-body problem, on the motion of an infinitesimal body under the gravity of Sun and Earth. This can be described by a 3-degree of freedom Hamiltonian system. We fix an energy ...
