Stability of Hamiltonian systems which are close to integrable : introduction to KAM and Nekhoroshev theory

Abstract:
We give a panorama of classical theories of stability of Hamiltonian systems close to integrable which are of two kind :
– Stability in measure over infinite time (KAM theory).
– Effective stability over finite but very long time (Nekhoroshev theory)
