A characterization of irreducible symmetric spaces
and Euclidean buildings of higher rank by their
asymptotic geometry
Bernhard Leeb*
June 17, 1997
Abstract. We study geodesically complete and locally compact Hadamard spaces
X whose Tits boundary is a connected irreducible spherical building. We show that
X is symmetric iff complete geodesies in X do not branch and a Euclidean building
otherwise. Furthermore, every boundary equivalence (cone topology homeomorphism
preserving the Tits metric) between two such spaces is induced by a homothety. As
an application, we can extend the Mostow and Prasad rigidity theorems to com-
pact singular (orbi)spaces of nonpositive curvature which are homotopy equivalent
to a quotient of a symmetric space or Euclidean building by a cocompact group of
isometries.
