Hölder differentiability of self-conformal devil's staircases

  • SASCHA TROSCHEIT (a1)
Abstract

In this paper we consider the probability distribution function of a Gibbs measure supported on a self-conformal set given by an iterated function system (devil's staircase) applied to a compact subset of ${\mathbb R}$ . We use thermodynamic multifractal formalism to calculate the Hausdorff dimension of the sets Sα0, Sα and Sα, the set of points at which this function has, respectively, Hölder derivative 0, ∞ or no derivative in the general sense. This extends recent work by Darst, Dekking, Falconer, Kesseböhmer and Stratmann, and Yao, Zhang and Li by considering arbitrary such Gibbs measures given by a potential function independent of the geometric potential.
