摘要
证明了对于实二次族在参数空间存在正Lebesgue测度集合E,使得E中几乎所有的参数,相应的映射在不变测度的支集上具有稠密的临界轨道;还证明了E中存在稠密集合使得相应映射的临界轨道进入它的反向不动点.
For the so-called quadratic family , it is proved that, there exists a positive Lebesgue mea- sure set E in the parameter space such that the corresponding map has a dense critical orbit in the support set of the invariant - measure for all parameters in E; it is also proved that there is a dense set in K such that the critical orbit of the corresponding map enter the reversed fixed point.
