关于李超代数的一类Fock-like表示

On a class of Fock-like representations for Lie Superalgebras

K. Kanakoglou, A. Herrera-Aguilar

摘要:

利用李超代数(LS)实现通过相对抛物集代数$P_{BF}$,结合早期的结果的Fock-like表示的$P_{BF}^{(1,1)}$,我们继续建设的Fock-like表示的LS族:这些是无限维的,可分解的超表示,这是参数化的值的正整数$p$。它们可以为任何LS $L$构造,或者从给定的$L$的2维$\mathbb{Z}_{2}$ -分级表示开始,或者使用其包含作为$P_{BF}^{(1,1)}$的子代数。作为应用,我们继续研究分解关于各种低维李代数和超代数。

英文摘要:

Utilizing Lie superalgebra (LS) realizations via the Relative Parabose Set algebra $P_{BF}$, combined with earlier results on the Fock-like representations of $P_{BF}^{(1,1)}$, we proceed to the construction of a family of Fock-like representations of LSs: these are infinite dimensional, decomposable super-representations, which are parameterized by the value of a positive integer $p$. They can be constructed for any LS $L$, either initiating from a given 2-dimensional, $\mathbb{Z}_{2}$-graded representation of $L$ or using its inclusion as a subalgebra of $P_{BF}^{(1,1)}$. As an application we proceed in studying decompositions with respect to various low-dimensional Lie algebras and superalgebras.
