论文摘要
让$ g $成为一个简单的代数伴随类型$ \ mathbb {c} $的复数，$ b $是$ g $的borel子组，其中包含最大圆环$ t $g。$ $g。$ $g。$在本文中，我们显示$α$是一个$ $ $ $ $ $ b $ b $ b $ q po $ q， $ x_ {q}（w）$ g/q $中的$，使得$ g $的最小抛物线子组$p_α$是连接的组件，包含$ x_ {q}（q}（w）的所有代数自动形态的同一群体的身份自动形态。
Let $G$ be a simple algebraic group of adjoint type over the field $\mathbb{C}$ of complex numbers, $B$ be a Borel subgroup of $G$ containing a maximal torus $T$ of $G.$ In this article, we show that $α$ is a co-minuscule root if and only if for any parabolic subgroup $Q$ containing $B$ properly, there is no Schubert variety $X_{Q}(w)$ in $G/Q$ such that the minimal parabolic subgroup $P_α$ of $G$ is the connected component, containing the identity automorphism of the group of all algebraic automorphisms of $X_{Q}(w).$
