Prerequisites:

Linear algebra and calculus with functions of several variables. 
Target skills and knowledge:

This course provides an introduction to the study of the ordinary and partial differential equations with the modern point of view of
dynamical systems. Examples from Astronomy and from Physics will
be considered. 
Examination methods:

Written examination 
Assessment criteria:

Evaluation of the written examination. 
Course unit contents:

1. Ordinary differential equations: Cauchy theorem, phasespace flow, dependence on the initial conditions; linear equations; phaseportraits, first integrals; equilibrium points; linearizations, stable, center and unstable spaces.
2. Integrable systems: elementary examples from population dynamics, from Mechanics and from Astronomy; integrability of mechanical systems, actionangle variables, examples.
3. Nonintegrable Systems: discrete dynamical systems, Poincare' sections; bifurcations, elementary examples. Stable and Unstable manifols, homoclinic chaos; Lyapunov exponents, the forced pendulum and other examples; Center manifolds and partial hyperbolicity. The three bodyproblem, the Lagrange equilibria,
Laypunov orbits, the tube manifolds.
