摘要:

本文研究了Zuckerman导出函子(g,K)-模块A_q(λ)到g'的限制,其中(g,g')是简约李代数的对称对。当限制分解为不可约(g',K')-模块时,我们给出了分支定律的上界。特别地,我们证明了每个出现在限制中的(g',K')-模块同构于一个parabolic子代数q'的A_q'(λ')的子模块,并确定了它们的关联奇点。为了证明,我们通过D-模在复部分旗流形上构造了A_q(λ)。

英文摘要:

In this article, we study the restriction of Zuckerman's derived functor (g,K)-modules A_q(λ) to g' for symmetric pairs of reductive Lie algebras (g,g'). When the restriction decomposes into irreducible (g',K')-modules, we give an upper bound for the branching law. In particular, we prove that each (g',K')-module occurring in the restriction is isomorphic to a submodule of A_q'(λ') for a parabolic subalgebra q' of g', and determine their associated varieties. For the proof, we construct A_q(λ) on complex partial flag varieties by using D-modules.
