Transitivity and homoclinic classes for singular-hyperbolic systems

Original · EN

A singular hyperbolic set is a partially hyperbolic set with singularities (all hyperbolic) and volume expanding central direction MPP1. We study connected, singular-hyperbolic, attracting sets with dense closed orbits and only one singularity. These sets are shown to be transitive for most Cʳ flows in the Baire's second category sence. In general these sets are shown to be either transitive or the union of two homoclinic classes. In the later case we prove the existence of finitely many homoclinic classes. Our results generalize for singular-hyperbolic systems a well known result for hyperbolic systems in N.
