Scaling properties of the thue–morse measure

Abstract: The classic Thue-Morse measure is a paradigmatic example of a purely singular continuous probability measure on the unit interval. Since it has a representation as an infinite Riesz product, many aspects of this measure have been studied in the past, including various scaling properties and a partly heuristic multifractal analysis. Some of the difficulties emerge from the appearance of an unbounded potential in the thermodynamic formalism. It is the purpose of this article to review and prove some of the obser… Show more

“…holds for all 1 ≤ i, j ≤ N , where α i = dens(Λ i )/dens (W j ) . This proportionality of measures matches nicely with the density formula δ P δ Q {0} = dens(P) dens(Q) (7) for Meyer sets P and Q that define uniquely ergodic Delone dynamical systems. With μ = δ P and ν = δ Q , this relation follows from the complex polarisation identity…”

“…The period doubling sequence, which is limit periodic, shows k 2 -scaling, and a range of scaling exponents is accessible for substitutions of more than two letters. For the Thue-Morse sequence, which is the paradigm of an inflation structure with singular continuous diffraction, we do not obtain a power law, but an exponential scaling behaviour which decays faster than any power; see also Baake, Gohlke et al (2019) for more on the scaling of the spectrum for this system. Finally, the Rudin-Shapiro sequence, which has an absolutely continuous spectrum, shows a linear scaling behaviour, due to the constant density of its diffraction measure.…”
