Universally polar cohomogeneity two Riemannian manifolds of constant negative curvature.

In this paper, we suppose that M is a Riemannian manifold of constant negative curvature under the action of a Lie subgroup G of IsoðMÞ such that the maximum of the dimension of the orbits is dim M - 2. Then, we study topological properties of M under some conditions. [ABSTRACT FROM AUTHOR]
