Nous étudions la relation entre les exposants critiques et les dimensions de Hausdorff des ensembles limites pour les représentations projectivement Anosov. Nous prouvons que la dimension de Hausdorff de l’ensemble limite symétrique dans P(ℝ n )×P(ℝ n * ) est bornée par deux exposants critiques associés respectivement à un plus haut poids et à une racine simple.

We study the relation between critical exponents and Hausdorff dimensions of limit sets for projective Anosov representations. We prove that the Hausdorff dimension of the symmetric limit set in P(ℝ n )×P(ℝ n * ) is bounded between two critical exponents associated respectively to a highest weight and a simple root.
