Nous calculons presque sûrement la dimension de Hausdorff de l’ensemble de recouvrement aléatoire dans le tore de dimension , où sont des parallélépipèdes, ou plus généralement, des images linéaires d’un ensemble d’intérieur non vide et 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 in -dimensional torus , where the sets are parallelepipeds, or more generally, linear images of a set with nonempty interior, and 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.
