Symplectic Dynamics Working Group

Through geometrical models, perturbation techniques and sometimes analytical approaches, it has been possible to establish a dictionary between "a taxonomy of generic dynamical phenomenons" and a list of "simple mechanisms or dynamical configurations" responsible for such phenomenons. I will try to explain that approach in a general context and we will focus on the case of symplectic and Hamiltonian dynamics and in some cases, to their geodesic flows counterpart.
