Geodesics in a Manifold with Heisenberg Group as Boundary

[摘要] The Heisenberg group is considered as the boundary of a manifold. A classof hypersurfaces in this manifold can be regarded as copies of the Heisenberggroup. The properties of geodesics in the interior and on the hypersurfacesare worked out in detail. These properties are strongly related to those ofthe Heisenberg group.
