关于抛物李代数的导子

On derivations of parabolic Lie algebras

Daniel Brice

摘要:

设$\mathfrak{g}$是代数闭的特征零域或$\mathbb{R}$上的约化李代数.设$\mathfrak{q}$是$\mathfrak{g}$的抛物子代数.我们通过将导子代数分解为两个理想的直和来刻画$\mathfrak{q}$的导子:其中一个理想是伴随表示的像,另一个理想由$\mathfrak{q}$上映射到$\mathfrak{q}$中心的所有线性变换组成,并将$\mathfrak{q}$的导出代数映射到$0$ .

英文摘要:

Let $\mathfrak{g}$ be a reductive Lie algebra over an algebraically closed, characteristic zero field or over $\mathbb{R}$. Let $\mathfrak{q}$ be a parabolic subalgebra of $\mathfrak{g}$. We characterize the derivations of $\mathfrak{q}$ by decomposing the derivation algebra as the direct sum of two ideals: one of which being the image of the adjoint representation and the other consisting of all linear transformations on $\mathfrak{q}$ that map into the center of $\mathfrak{q}$ and map the derived algebra of $\mathfrak{q}$ to $0$.
