Multivariate multifractal analysis of L{é}vy functions. Part II: Validity of the multifractal formalism
Stéphane Jaffard, Lingmin Liao, Qian Zhang
In this article, we determine the multivariate multifractal Legendre spectra of shifted L{é}vy functions. This allows us to explore how the validity of the multivariate multifract…

Multivariate multifractal analysis of Levy functions. Part I: Determination of multifractal spectra
Stéphane Jaffard, Lingmin Liao, Qian Zhang
We study the sets of points where a Lévy function and a translated Lévy function share a given couple of H\''older exponents, and we investigate how their Hausdorff dimensions de…
