Abstract:
We give a topological description of cohomogeneity two Riemannian manifolds of negative curvature which are either locally symmetric or there is no singular orbit of positive
dimension.
As an application, we classify cohomogeneity k, k<4, Riemannian manifolds of constant negative curvature.
