Etant donné un processus multiplicatif fractionnaire bi-dimensionnel (F t ) t[0,1] déterminé par deux exposants de Hurst H 1 et H 2 , nous montrons l’existence d’un résultat uniforme pour la dimension de Hausdorff des images des sous-ensembles de [0,1] par F si et seulement si H 1 =H 2 .

Given a two-dimensional fractional multiplicative process (F t ) t[0,1] determined by two Hurst exponents H 1 and H 2 , we show that there is an associated uniform Hausdorff dimension result for the images of subsets of [0,1] by F if and only if H 1 =H 2 .
