The study on the scenarios for chaotic itinerancy

关于混沌巡游的机制，我们提出了四种情景：1.出现三元组(Milnor吸引子，筛子盆地，混沌不变集)；2.存在入口和出口集出现开关间歇的不变集；3.正常双曲不变流形的出现；4.具有多个稳定状态的分形盆边界的存在.还指出了异维循环现象下的另一种可能性。

We have proposed four scenarios on the mechanisms of chaotic itinerancy : 1. the appearance of triplet {Milnor attractors, riddled basin, chaotic invariant set} ; 2. the presence of the invariant set on which the entrance and the exit sets appears such as on-off intermittency; 3. the appearance of normally hyperbolic invariant manifolds ; 4. the presence of fractal basin boundaries with multiple stable states. The other possibility under the appearance of hetero-dimensional cycle was also pointed out.
