Abstract:This paper develops new techniques for studying smooth dynamical systems in the presence of a Carnot-Carathéodory metric. Principally, we employ the theory of Margulis-Mostow, Métivier, Mitchell and Pansu on tangent cones to establish resonances between Lyapunov exponents. We apply these results in three different settings. First, we explore rigidity properties of smooth dominated splittings for Anosov diffeomorphisms and flows via associated smooth Carnot-Carathéodory metrics. Second, we obtain local rigidity… Show more
