Other Research Interests

Dynamical Systems

  1. Study of invariant manifolds associated to non normally hyperbolic objects: existence, regularity and persistence on perturbations.
  2. Singular perturbation theory and beyond all orders phenomenon. The purpose is twofold: to provide rigorous proofs and to find new scenarios where this phenomenon occurs.
  3. Arnold’s diffusion by means of resonances in the classical Arnold’s example.
  4. Applications of the previous explained theoretical frameworks to physical problems: spiral waves, celestial mechanics with special interest in some instances of the n-body problem, etc.
