导论.这是第一部分的继续,第一部分载于同一份《日刊》。在前一篇文章中,我们考虑了紧致单连通不可约黎曼对称空间M上的Grassmann丛GS(TM),并通过M的等距群G考虑了GS(TM)中的G-轨道CV。每一个Q?我们可以在M中定义一类子流形,称为^-几何。我们还假设^是一个G-轨道,其中包含一个^维强曲率不变子空间。那我呢?对应于紧半单李代数g和两个交换对合σ,r的PSLA(g,σ,T). PSLA在代数上分为内型PSLA和外型PSLA。我们在这篇文章中的目的是证明以下几点
Introduction. This is a continuation of Part I, which appears in the same Journal. In the previous paper we take a Grassmann bundle GS(TM) over a compact simply connected irreducible riemannian symmetric space M and consider a G-orbit CV in GS(TM) by the isometry group G of M. For each Q? we can define a class of submanifolds in M, so is called, a ^-geometry. We moreover assume that ^ is a G-orbit which contains an ^-dimensional strongly curvature-invariant subspace. Then ^l? corresponds to a PSLA (g, σ, T) of compact semisimple Lie algebra g and two commutative involutions σ, r. PSLA's are algebraicaly divided into those of inner type and those of outer type. Our aim in this article is to prove the following
