Title: Dynamical Instability of nearly integrable Hamiltonian systems
Abstract: Arnold diffusion is one of the most important problems in the field of dynamical systems and has puzzled us for half a century. It asks whether it is typical phenomenon that a higher-dimensional problems is topological instability: through an arbitrarily small neighborhood of any point there passes a phase trajectories along which the slow variables drift away from the initial value by a quantity of order 1.
In this talk, I shall survey recent progress on the topic and sketch our proof of Arnold diffusion in nearly integrable systems with three degrees of freedom.
