Abstract

Nous calculons presque sûrement la dimension de Hausdorff de l’ensemble de recouvrement aléatoire ${lim sup}_{n \to \infty} (g_{n} + ξ_{n})$ dans le tore $𝕋^{d}$ de dimension $d$ , où $g_{n} \subset 𝕋^{d}$ sont des parallélépipèdes, ou plus généralement, des images linéaires d’un ensemble d’intérieur non vide et $ξ_{n} \in 𝕋^{d}$ sont des points aléatoires indépendants et uniformément distribués. La formule de dimension, exprimée en fonction des valeurs singulières des applications linéaires, est valable à condition que la suite de ces valeurs singulières soit décroissante.

We calculate the almost sure Hausdorff dimension of the random covering set ${lim sup}_{n \to \infty} (g_{n} + ξ_{n})$ in $d$ -dimensional torus $𝕋^{d}$ , where the sets $g_{n} \subset 𝕋^{d}$ are parallelepipeds, or more generally, linear images of a set with nonempty interior, and $ξ_{n} \in 𝕋^{d}$ are independent and uniformly distributed random points. The dimension formula, derived from the singular values of the linear mappings, holds provided that the sequences of the singular values are decreasing.
