Contents
- Preliminary statements about discrete and continuous dynamical systems. The skeleton of a system: invariant objects.
- Some paradigmatic examples: Henon, standard and separatrix maps, Duffing equations, Rossler model, etc.
- Fixed points/stationary states. Local analysis of stability. A first approach to Normal Forms. Bifurcations and unfoldings.
- Hyperbolicity: stable and unstable manifolds. Normally hyperbolic invariant manifolds (NHIM). Homoclinic and heteroclinic phenomena.
- Chaos: symbolic dynamics, topological entropy, invariant Cantorian sets.
- Introduction to invariant measures and to ergodic theory.
- Averaging and normal forms. The problem of small divisors and the Diophantine conditions. Slow-fast systems.
- Hamiltonian systems. Integrability versus non-integrability. KAM theory. Destruction of invariant tori. Aubry-Mather invariant sets. Diffusion mechanisms. The role of the splitting of the invariant manifolds of NHIM.
- Some topics in Celestial Mechanics and Astrodynamics. Invariant objects of the N-body problem, and applications to Astronomy and Space Science.
- Dissipative systems. Invariant measures, and strange attractors.
- Evolution PDE analyzed using dynamical systems tools.
