Uniformly quasiregular maps with toroidal Julia sets
2012
Conformal Geometry and Dynamics
Preserved Fulltext
We construct the first examples of uniformly quasiregular mappings that have a 2-torus as the Julia set. ...
The spaces supporting this type of mappings include the Hopf link complement and its lens space quotients. ...

Using an analogy of the Lattès' construction of chaotic rational functions, we show that there are uniformly quasiregular mappings of the nsphere R n whose Julia set is the whole sphere. ...
Moreover there are analogues of power mappings, uniformly quasiregular mappings whose Julia set is S n−1 and its complement in S n consists of two superattracting basins. ...
The dynamical behaviour of such a mapping splits the sphere into two parts: the Fatou set F (f ), which is the set of points x for which {f k } is a normal family in a neighborhood of x, and the Julia ...

In this paper, we prove the analogous statement in the setting of strongly automorphic quasiregular mappings and uniformly quasiregular mappings in R^n. ...
We further give a classification of the behaviour of uniformly quasiregular mappings on their Julia set when the Julia set is a quasisphere, quasidisk or all of R^n and the Julia set coincides with the ...
Given f, x0 and ϕ, there are infinitely many possibilities for L. In the plane, a linearizer
is normalized via L0 (0) = 1. Note that such a normalization is unavailable for quasiregular
mappings. ...

This generalises and gives a new proof of the analogous classification for fibered 3-manifolds. Various applications are given. ...
In particular, we deduce that rigidity results for Gromov hyperbolic groups hold for the above mapping tori with trivial center. ...
Any quasiregular map is open and discrete, i.e., the preimage of any point consists of isolated points. In particular, the preimage of any point under a proper quasiregular map is a finite set. ...
