Dimension gap and variational principle for Anosov representations
Abstract
We consider a representation of a finitely generated CAT(--K) group in SL(d, R) that is Zariski dense and k-Anosov for at least two values of k. We exhibit a gap for the Minkowski dimension of minimal sets for the action of on flags spaces. The proof uses a variational principle for the action on partial flags.
