研究了Kac-Moody代数(A)的群G的可积最高权模中最高权向量的轨道.我们得到的应用程序的几何结构的相关标志品种和代数结构的[unk](A)。特别地,我们证明了[unk](A)的Cartan和Borel子代数的共轭定理,使得Cartan矩阵A是[unk](A)的不变量。
We study the orbit of a highest-weight vector in an integrable highest-weight module of the group G associated to a Kac-Moody algebra [unk](A). We obtain applications to the geometric structure of the associated flag varieties and to the algebraic structure of [unk](A). In particular, we prove conjugacy theorems for Cartan and Borel subalgebras of [unk](A), so that the Cartan matrix A is an invariant of [unk](A).
