The school aims to introduce graduate students and young researchers to the modern theory of dynamical systems and its applications, with a focus on geometric, topological, and numerical methods. The courses will be focused on some key topics in low and high dimensional dynamics, including Hamiltonian systems, Celestial Mechanics, statistical properties of dynamical sysyems and their relation with the underlying geometric structures. The participants will be provided with an introduction to the basic material with the necessary background, before proceeding with the more advanced topics.
