Zero Lyapunov exponents or uniform hyperbolicity in generic 4-dimensional Hamiltonian dynamical systems

João Lopes Dias

Abstract: We will present some dynamical properties that hold for C2 generic Hamiltonian systems in 4-dimensional compact domains. Namely, we find the existence of a dichotomy: zero Lyapunov exponents (meaning, no 'chaos') or else uniform hyperbolicity (meaning, 'full chaos'). Part of the talk will be devoted to introducing the above dynamical concepts.
