Heaviness in Circle Rotations

نویسنده

چکیده

We are concerned with describing the structure of the set of points in the unit interval which, when subjected to rotation by irrational α modulo one, for all finite portions of the orbit contain at least as many points in the bottom half of the interval as in the top half. Specifically, an inductive procedure for describing the set based on the continued fraction expansion of α is developed, leading into a discussion of the Hausdorff dimension of this set. Depending on the parameter α, all possible dimensions may be achieved, and the essential infimum (with respect to α) of this dimension is positive.

Heaviness in Toral Rotations

Abstract. We investigate the dimension of the set of points in the d-torus which have the property that their orbit under rotation by some α hits a fixed closed target A more often than expected for all finite initial portions. An upper bound for the lower Minkowski dimension of this strictly heavy set H(A,α) is found in terms of the upper Minkowski dimension of ∂A, as well as k, the Diophantin...

On Circle Rotations and the Shrinking Target Properties

We give a necessary and sufficient condition for a circle rotation to have the s-exponent monotone shrinking target property (sMSTP), and, thereby, we generalize a result for s = 1 that was established by J. Kurzweil and rediscovered by B. Fayad. As another application of our technique, we obtain a new, very short, proof of a known result, which concerns the behavior of irrational rotations and...

A Denjoy Type Theorem for Commuting Circle Diffeomorphisms with Derivatives Having Different Hölder Differentiability Classes

Let d > 2 be an integer number, and let fk, k ∈ {1, . . . , d}, be Ck commuting circle diffeomorphisms, with τk ∈ ]0, 1[ and τ1 + · · · + τd > 1. We prove that if the rotation numbers of the fk’s are independent over the rationals (that is, if the corresponding action of Z n on the circle is free), then they are simultaneously (topologically) conjugate to rotations. 2000 Math. Subj. Class. 22F0...

Sarnak’s Conjecture about Möbius Function Randomness in Deterministic Dynamical Systems

The thesis in hand deals with a conjecture of Sarnak from 2010 about the orthogonality of sequences induced by deterministic dynamical systems to the Möbius μ-function. Its main results are the ergodic theorem with Möbius weights, which is a measure theoretic (weaker) version of Sarnak’s conjecture, and the already assured validity of Sarnak’s conjecture in special cases, where we have exemplar...

Palindromic complexity of codings of rotations

We study the palindromic complexity of infinite words obtained by coding rotations on partitions of the unit circle by inspecting the return words. The main result is that every coding of rotations on two intervals is full, that is, it realizes the maximal palindromic complexity. As a byproduct, a slight improvement about return words in codings of rotations is obtained: every factor of a codin...
