李超代数振子模的Kostant同调公式

Kostant homology formulas for oscillator modules of Lie superalgebras

Shun-Jen Cheng, Jae-Hoon Kwon, Weiqiang Wang

摘要:

利用无限维李代数的Howe对偶,给出了有限维一般线性超代数和正交辛超代数的振子模的特征标和Kostant ${\mathfrak u}$ -同调群的计算公式.将这些李超代数专门化为李代数,我们以一种新的方式恢复了Hermitian对称对的可酉化的最高权表示的Kostant同调群的公式。此外,还构造了与上述${\mathfrak u}$ -同调计算相关的两个新的约化对偶对。

英文摘要:

We provide a systematic approach to obtain formulas for characters and Kostant ${\mathfrak u}$-homology groups of the oscillator modules of the finite dimensional general linear and ortho-symplectic superalgebras, via Howe dualities for infinite dimensional Lie algebras. Specializing these Lie superalgebras to Lie algebras, we recover, in a new way, formulas for Kostant homology groups of unitarizable highest weight representations of Hermitian symmetric pairs. In addition, two new reductive dual pairs related to the above-mentioned ${\mathfrak u}$-homology computation are worked out.
