We prove a result motivated by Williams's classification of expanding attractors and the Franks-Newhouse Theorem on codimension-1 Anosov diffeomorphisms: If Λ is a topologically mixing hyperbolic attractor such that dim Eu{up harpoon right}Λ = 1, then either Λ is expanding or is homeomorphic to a compact abelian group (a toral solenoid). In the latter case, f {up harpoon right}Λ is conjugate to a group automorphism. As a corollary, we obtain a classification of all 2-dimensional basic sets in 3-manifolds. Furthermore, we classify all topologically mixing hyperbolic attractors in 3-manifolds in terms of the classically studied examples, answering a question of Bonatti in [1].
