We investigate local dynamics of uniformly quasiregular mappings, give new examples and show in particular that there is no quasiconformal analogue of the Leau-Fatou linearization of parabolic dynamics.

“…Nevertheless, it is a difficult task to write down explicit examples of uqr mappings having degree at least two. This was first done by Iwaniec and Martin [9], and subsequently other examples were given in [14], [17], [18]. In particular, Mayer's paper [17] exhibits the higher-dimensional Lattès maps.…”
“…In 1997 and 1998, Mayer discovered an important family of examples of uniformly quasiregular mappings; see [10] and [11]. They are analogues of the rational functions that are called critically finite with parabolic orbifold.…”

“…Power mapping. Let us first show how a 4-to-1 uqr mapping arises on S 3 via the Zorich mapping, the higher dimensional counterpart of the planar exponential function, as presented by Rickman [13, p. 15]) and later Mayer [10]. Denote the Zorich mapping by h Z : R 3 → R 3 \ {0}.…”

A uniformly quasiregular mapping acting on a compact Riemannian manifold distorts the metric by a bounded amount, independently of the number of iterates. Such maps are rational with respect to some measurable conformal structure and there is a Fatou-Julia type theory associated with the dynamical system obtained by iterating these mappings. We study a rich subclass of uniformly quasiregular mappings that can be produced using an analogy of classical Lattès' construction of chaotic rational functions acting on the extended planeC. We show that there is a plenitude of compact manifolds that support these mappings. Moreover, we find that in some cases there are alternative ways to construct this type of mapping with different Julia sets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
