Backward iteration in the unit ball

Complex Variables 2015-03-13 v4

Abstract

We will consider iteration of an analytic self-map ff of the unit ball in CN\mathbb{C}^N. Many facts were established about such dynamics in the 1-dimensional case (i.e. for self-maps of the unit disk), and we will generalize some of them in higher dimensions. In particular, in the case when ff is hyperbolic or elliptic, it will be shown that backward-iteration sequences with bounded hyperbolic step converge to a point on the boundary. These points will be called boundary repelling fixed points and will possess several nice properties. At each isolated boundary repelling fixed point we will also construct a (semi) conjugation of ff to an automorphism via an analytic intertwining map. We will finish with some new examples.
