Résumé
Abstract

Supposons que les dérivées pures (pas nécéssairement du même ordre) d'une fonction sur $R^{n}$ soient des mesures de Radon finies. On montre que leur dimension inférieure de Hausdorf est alors au moins $n - 1$ .

We prove that if pure derivatives of a function on $R^{n}$ are complex measures, then their lower Hausdorff dimension is at least $n - 1$ . The derivatives with respect to different coordinates may be of different order.
