$asl_2$的表示
Representations of $asl_2$
摘要:
研究了Ovsienko引入的单李反代数$asl_2$的表示.我们表明,表示$asl_2$密切相关的著名鬼卡西米尔元素的泛包络代数$osp(1|2)$。我们证明了$asl_2$没有非平凡的有限维表示,我们定义和分类一些特定的无限维表示,我们称之为加权表示。
英文摘要:
We study representations of the simple Lie antialgebra $asl_2$ introduced by Ovsienko. We show that representations of $asl_2$ are closely related to the famous ghost Casimir element of the universal enveloping algebra $osp(1|2)$. We prove that $asl_2$ has no non-trivial finite-dimensional representations; we define and classify some particular infinite-dimensional representations that we call weighted representations.
