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 with open questions and exercises on the topics discussed during lectures. 
Assessment criteria:

The student is asked to use the correct terminology, know the full program of the lectures, be able to link the different topics discussed during lectures and be able to critically apply the methods of dynamical systems. 
Course unit contents:

The course is given for both students of the Master Degree in Astronomy and Master Degree in Mathematical Engineering. Topics in sections 4) and 5) are only students of the Master Degree in Astronomy, whereas topics in section 6) are only for students of the Master Degree in Mathematical Engineering.
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, PoincarĂ© 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,
Lyapunov orbits, the tube manifolds.
4) Linear PDEs of first and second order, wellposed problems,
the vibrating string, 1dimensional wave equation, normal modes of vibrations, heat equation, Fourier series, 2dimensional wave equation, Laplace operator and polar coordinates, separation of variables, Bessel functions, eigenfunctions of the Laplacian operator.
5) Laplace operator and spherical coordinates, separation of variables, Legendre polynomials and associate functions, Spherical harmonics, multipole expansions, L2 operatoreigenvalues and eigenfunctions, complete solution of the wave equation in space, Schrodinger polynomials.
6) Examples and Applications: examples of analysis of three and four dimensional systems; limit cycles; the Lorenz system, the threebody problem; examples from fluid dynamics, non autonomous dynamical systems, chaos indicators, Lagrangian Coherent Structures.
