Estimations de la dimension inférieure et de la dimension supérieure des mesures
Résumé
In good cases, we prove that the function $\tau$ which appears in multifractal formalism is adapted to calculate the lower and the upper dimension of a measure. Then, we are able to prove the derivability of $\tau$ for quasi-Bernoulli measures, thus precising some of Brown Michon and Peyrière results concerning the multifractal analysis of these measures.
