Secular instability in the three-body problem
Fejoz, J.; Guàrdia Munarriz, Marcel (2016-02-03)
Article
Accés obert© 2016 European Union Consider the three-body problem, in the regime where one body revolves far away around the other two, in space, the masses of the bodies being arbitrary but fixed; in this regime, there are no resonances ... -

Splitting of separatrices in the resonances of nearly integrable Hamiltonian Systems of one and a half degrees of freedom
Guàrdia Munarriz, Marcel (2013)
Article
Accés obertIn this paper we consider general nearly integrable analytic Hamiltonian systems of one and a half degrees of freedom which are a trigonometric polynomial in the angular state variable. In the resonances of these systems ... -
Strong nonlinear instability and growth of Sobolev norms near quasiperiodic finite gap tori for the 2D cubic NLS equation
Guàrdia Munarriz, Marcel; Hani, Zaher; Haus, Emanuele; Maspero, Alberto; Procesi, Michela (2022-03-03)
Article
Accés obertWe consider the defocusing cubic nonlinear Schrödinger equation (NLS) on the two-dimensional torus. The equation admits a special family of elliptic invariant quasiperiodic tori called finite-gap solutions. These are ... -
Symbolic dynamics in the restricted elliptic isosceles three body problem
Guàrdia Munarriz, Marcel; Paradela Díaz, Jaime; Martínez-Seara Alonso, M. Teresa; Vidal Díaz, Claudio (2021-09-05)
Article
Accés restringit per política de l'editorialThe restricted elliptic isosceles three body problem (REI3BP) models the motion of a massless body under the influence of the Newtonian gravitational force caused by two other bodies called the primaries. The primaries of ...
