摘要

在本文中,我们研究了有理 Collet-Eckmann 映射,对于这些映射,Julia 集不是整个球面,而且临界点以缓慢的速度反复出现。在临界点阶数固定的族中,我们证明了这类映射是双曲映射的勒贝格密度点。特别是,如果所有临界点都是简单的,这些映射就是任意度 d⩾2$d \geqslant 2$ 的有理映射全空间中双曲映射的 Lebesgue 密度点。

Slowly recurrent Collet–Eckmann maps with non-empty Fatou set
In this paper, we study rational Collet–Eckmann maps for which the Julia set is not the whole sphere and for which the critical points are recurrent at a slow rate. In families where the orders of the critical points are fixed, we prove that such maps are Lebesgue density points of hyperbolic maps. In particular, if all critical points are simple, these maps are Lebesgue density points of hyperbolic maps in the full space of rational maps of any degree d 2 $d \geqslant 2$ .
