非紧李群的不变微分算子:约化的SU(4,4)重态

Invariant Differential Operators for Non-Compact Lie Groups: the Reduced SU(4,4) Multiplets

V. K. Dobrev

摘要:

本文以非紧代数$su(n,n)$为例,继续系统地构造不变微分算子。前面已经给出了$n\leq 4$的不可分解初等表示的主要多重态和$n=2,3$的约化多重态。在这里,我们给所有减少多重包含物理相关的表示,包括最小的$n=4$。由于最近建立的抛物关系的结果也是有效的代数$sl(8,\mathbb{R})$和$su^*(8)$与适当选择的极大抛物子代数。

英文摘要:

In the present paper we continue the project of systematic construction of invariant differential operators on the example of the non-compact algebras $su(n,n)$. Earlier were given the main multiplets of indecomposable elementary representations for $n\leq 4$, and the reduced ones for $n=2,3$. Here we give all reduced multiplets containing physically relevant representations including the minimal ones for $n=4$. Due to the recently established parabolic relations the results are valid also for the algebras $sl(8,\mathbb{R})$ and $su^*(8)$ with suitably chosen maximal parabolic subalgebras.
