本文用初等几何和拓扑方法研究了对称空间的粗几何问题。我们的结果是强大的,足以适用于非余紧格在高秩对称空间,如SL(n,2),n > 3:定理8.1是一个重要的步骤,证明拟等距刚性的这种格([E])。本文还对Kleiner-Leeb关于高秩对称空间的拟等距刚性定理([KL])给出了一个不同的有效证明。
In this paper we use elementary geometrical and topological methods to study some questions about the coarse geometry of symmetric spaces. Our results are powerful enough to apply to noncocompact lattices in higher rank symmetric spaces, such as SL(n, 2), n > 3: Theorem 8.1 is a major step towards the proof of quasiisometric rigidity of such lattices ([E]). We also give a different, and effective, proof of the theorem of Kleiner-Leeb on the quasi-isometric rigidity of higher rank symmetric spaces ([KL]).
