Rafael de la Llave (University of Texas at Austin): Some geometric mechanisms of instability in Hamiltonian dynamical systems

Abstract. There are several geometric structures that provide road maps for trajectories to perform several wide excursions in Hamiltonian dynamical systems. We want to present several of them, obtained in joint work with A. Delshams, M. Gidea, T. M. Seara.
