LIPSCHITZ LIMIT SETS REVISITED: HILBERT ENTROPY AND NON-DIFFERENTIABILITY

Résumé

We interpret the Hilbert entropy of a convex projective structure on a closed surface of higher genus as the Hausdorff dimension of the nondifferentiability points of the limit set in the full flag space F(R^3). Generalizations of this for hyperconvex representations are also discussed. An ingredient for the proofs is the concept of hyperplane conicality that we introduce for a θ-Anosov representation into a reductive real-algebraic Lie group G. In contrast with directional conicality, hyperplane-conical points always have full mass for the corresponding Patterson-Sullivan measures.
