题  目：限制性N体问题的近可积结构

报告人：张建路 (中科院数学所)

摘  要：In restricted N body problem, we can find a bunch of nearly integrable structures in certain domain of the phase space, e.g. the collision region, the infinity, etc. With the classical perturbative approach and the KAM method, we can construct a series of erratic orbits, for instance, the collision orbits, the oscillatory orbits and diffusion orbits so on. We will briefly give a survey on the quantitative aspect on all this amazing dynamic behaviors.
