A duality principle between Grassmann geometries on compact symmetric spaces and those on noncompact symmetric spaces is proved, which greatly facilitates the study of Grassmann geometry on symmetric spaces. Those Grassmann geometries on noncompact symmetric spaces which admit non-totally geodesic submanifold are also determined. 展开更多
