Julia Sets Are Uniformly Perfect
We prove that Julia sets are uniformly perfect in the sense of Pommerenke (Arch. Math. 32 (1979), 192-199). This implies that their linear density of loganthmic capacity is strictly positive, thus implying that Julia sets are regular in the sense of Dinchlet. Using this we obtain a formula for the entropy of invanant harmonic measures on Julia sets. As a corollary we give a very short proof of ...
متن کاملClassification of uniformly outer actions of Z on UHF algebras
We give a complete classification up to cocycle conjugacy of uniformly outer actions of Z on UHF algebras. In particular, it is shown that any two uniformly outer actions of Z on a UHF algebra of infinite type are cocycle conjugate. We also classify them up to outer conjugacy.
متن کاملFactor versus palindromic complexity of uniformly recurrent infinite words
We study the relation between the palindromic and factor complexity of infinite words. We show that for uniformly recurrent words one has P(n) + P(n + 1) ≤ ∆C(n) + 2, for all n ∈ N. For a large class of words it is a better estimate of the palindromic complexity in terms of the factor complexity then the one presented in [2]. We provide several examples of infinite words for which our estimate ...
متن کاملUniformly balanced words with linear complexity and prescribed letter frequencies
We consider the following problem. Let us fix a finite alphabet A = {1,2, · · · ,d}; for any d-uple of letter frequencies ( f1, · · · , fd) ∈ [0,1]d with ∑i=1 fi = 1, how to construct an infinite word u over the alphabet A satisfying the following conditions: u has linear complexity function, u is uniformly balanced, the letter frequencies in u are given by ( f1, · · · , fd). This paper investi...
متن کاملUniformly convex Banach spaces are reflexive - constructively
We propose a natural definition of what it means in a constructive context for a Banach space to be reflexive, and then prove a constructive counterpart of the MilmanPettis theorem that uniformly convex Banach spaces are reflexive. Our aim in this note is to present a fully constructive analysis of the Milman-Pettis theorem [11, 12, 9, 13]: a uniformly convex Banach space is reflexive. First, t...
