Multifractal formalism and anisotropic selfsimilar functions

In this paper we prove that the conjectures of Frisch and Parisi and Arneodo et al. (called the multifractal formalism for functions) may fail for some non-homogeneous selfsimilar functions on ℝ2. In these cases, we compute the correct spectrum of singularities and we show how the multifractal formalism must be modified.

Multifractal Formalism for generalized selfsimilar functions

Abstract

We study the Multifractal Formalism for certain classes of functions having selfsimilarity properties.

Etude du formalisme multifractal pour les fonctions

Summary The aim of this thesis is the multifractai analysis of selfsimilar functions and the study of the validity of the multifractai formalism. First, we determine the exact pointwise Holder regularity for functions such that locally the graph is roughly a contraction of the global graph, modulo an error; then we compute the Hausdorff dimensions of the sets of points which have the same Holder exponent; and finally we verify the conjectures of Frish and Parisi and the one of Arneodo, Bacry and Muzy, which relate these dimensions to some averaged quantities extracted from the function.
