区间分段扩张映射的吸引子

On the attractor of piecewise expanding maps of the interval

Gianluigi Del Magno, João Lopes Dias, Pedro Duarte, José Pedro Gaivão

摘要:

我们考虑区间上具有多个单调分支的分段扩张映射,并证明了它们是一般组合稳定的,即,遍历吸引子的数目和它们相应的混合周期在映射的小扰动下不改变。我们的方法提供了一个拓扑描述的吸引子,特别是,周期轨道的密度给出了一个初等的证明。

英文摘要:

We consider piecewise expanding maps of the interval with finitely many branches of monotonicity and show that they are generically combinatorially stable, i.e., the number of ergodic attractors and their corresponding mixing periods do not change under small perturbations of the map. Our methods provide a topological description of the attractor and, in particular, give an elementary proof of the density of periodic orbits.
