Abstract
Let be a smooth conservative diffeomorphism of a compact surface and let be a transitive horseshoe of . Given a smooth real function defined in and a small smooth conservative perturbation of , let and be respectively the Lagrange and Markov spectra associated to the hyperbolic continuation of the horseshoe and . We show that for generic choices of and , the Hausdorff dimension of the sets and are equal and determine a continuous function as varies; generalizing then the Cerqueira-Matheus-Moreira theorem to horseshoes with arbitrary Hausdorff dimension.
