Abstract

Let X, H+, H be vector fields tangent, respectively, to an Anosov flow and its expanding and contracting foliations in a compact three-dimensional manifold, with γ, α+, α one forms dual to them. If α+([H+, H]) = α([H+, H]) and γ([H+, H]) = α([X, H]) − α+([X, H+]), then the manifold has the structure of the unit tangent bundle of a Riemannian orbifold with geodesic flow field X.
