Multivariate multifractal analysis of L{é}vy functions. Part II: Validity of the multifractal formalism

Abstract: In this article, we determine the multivariate multifractal Legendre spectra of shifted L{\'e}vy functions. This allows us to explore how the validity of the multivariate multifractal formalism depends on the shift parameter. This article is a continuation of [10] where the corresponding bivariate multifractal spectra were explored.
