Resumen:
Our aim is to explain normal form technics that allow to study the long time behaviour of the solutions of some nolinear Hamiltonian PDEs. We are in particular interested in stability results. Our approach is centered on the Birkhoff normal form theorem that we will first state in finite dimension. Then, after giving some exemples of Hamiltonian PDEs, we present an abstract Birkhoff normal form theorem in infinite dimension and discuss the dynamical consequences for Hamiltonian PDEs.
