Julia Sets and Wild Cantor Sets
There exist uniformly quasiregular maps f : R → R whose Julia sets are wild Cantor sets.
متن کاملProof of the Branner-Hubbard conjecture on Cantor Julia sets
By means of a nested sequence of some critical pieces constructed by Kozlovski, Shen, and van Strien, and by using a covering lemma recently proved by Kahn and Lyubich, we prove that the Julia set of a polynomial is a Cantor set if and only if each component of the filledin Julia set containing critical points is aperiodic. This result was a conjecture raised by Branner and Hubbard in 1992.

Family of Invariant Cantor Sets as orbits of Differential Equations II: Julia Sets
The Julia set of the quadratic map fμ(z) = μz(1 − z) for μ not belonging to the Mandelbrot set is hyperbolic, thus varies continuously. It follows that a continuous curve in the exterior of the Mandelbrot set induces a continuous family of Julia sets. The focus of this article is to show that this family can be obtained explicitly by solving the initial value problem of a system of infinitely c...
متن کاملCantor sets
This paper deals with questions of how many compact subsets of certain kinds it takes to cover the space ω of irrationals, or certain of its subspaces. In particular, given f ∈ (ω\{0}), we consider compact sets of the form Q i∈ω Bi, where |Bi| = f(i) for all, or for infinitely many, i. We also consider “n-splitting” compact sets, i.e., compact sets K such that for any f ∈ K and i ∈ ω, |{g(i) : ...
