| Manifolds of nonpositive curvature and their buildings (1987) | |||||||||||||||
Abstract | |||||||||||||||
| Let M be a complete Riemannian manifold of bounded nonpositive sectional curvature and finite volume. We construct a topological Tits building A(~I) associated to the universal cover of M. If IV [ is irreducible and rank (M)>I 2, we show that A(~I) is a building canonically associated with a Lie group and hence that M is locally symmetric. | |||||||||||||||
