A torus manifold M is a 2n-dimensional orientable manifold with an effective action of an n-dimensional torus such that M T 6 ∅. In this paper we discuss the classification of torus manifolds which admit an invariant metric of non-negative curvature. If M is a torus manifold which admits such a metric, then M is diffeomorphic to a quotient of a free linear torus action on a product of spheres. We also classify rationally elliptic torus manifolds up to rational homotopy equivalence and homeomorphism.
