| Research Abstract |
We have studied the stochastic properties of chaotic dynamical systems in which very complex motions appear by the analysis of the hitting time, that is, the time in which an orbit hit to some fixed domain. Especially, in the case of non-uniformly hyperbolic dynamical system which is a "weak chaos", we showed that the different distribution from the one of the typical chaotic system appears. And, we also studied the stochastic properties of the meeting time distribution, that is, the time in which different orbits come close.
