HOMOGENEOUS RIEMANNIAN SPACES OF NEGATIVE CURVATURE

In this paper the structure of simply-transitive isometry groups of a Riemannian space with nonpositive curvature is studied. The results obtained are then applied to classify Riemannian spaces of negative curvature possessing a metabelian transitive isometry group and also to classify homogeneous Einstein spaces with nonpositive curvature and with dimension .Bibliography: 13 items.
