摘要
我们证明,与非退化约旦三重系统相关联的伪黎曼对称 R 空间的反交点集合满足以下两个性质:(1)任何反交点集合都包含在一个大反交点集合中;(2)任何两个大反交点集合都通过等距法相互转化。
Antipodal sets of pseudo-Riemannian symmetric R-spaces
We show that antipodal sets of pseudo-Riemannian symmetric R-spaces associated with non-degenerate Jordan triple systems satisfy the following two properties: (1) Any antipodal set is included in a great antipodal set, and (2) any two great antipodal sets are transformed into each other by an isometry.
