Typical Borel measures on $[0,1]d$ satisfy a multifractal formalism

Abstract

In this article, we prove that in the Baire category sense, measures supported by the unit cube of ${\mathbb{R}}^d$ typically satisfy a multifractal formalism. To achieve this, we compute explicitly the multifractal spectrum of such typical measures $\mu$. This spectrum appears to be linear with slope 1, starting from 0 at exponent 0, ending at dimension $d$ at exponent $d$, and it indeed coincides with the Legendre transform of the $L^q$-spectrum associated with typical measures $\mu$.
