本文首先为N=2 Neveu-Schwarz代数𝒞构造了大量简单限制模,这些模包含最高权模和Whittaker模;接着在特定条件下精确刻画𝒞上的简单限制模,建立简单𝒞-模为限制模的若干等价条件;最后证明,若𝒞的某个特定正根元素在简单𝒞-模V上局部有限作用,则V必为限制模。

英文摘要

In this paper, we first construct many simple restricted modules for the $N=2$ Neveu-Schwarz algebra $\mathcal{L}$. These modules contain the highest weight modules and Whittaker modules. Then we precisely characterize the simple restricted modules over $\mathcal{L}$ under certain conditions, and establish several equivalent conditions for a simple \(\mathcal{L}\)-module to be restricted. Finally, we prove that if one specific positive root element of $\mathcal{L}$ acts locally finitely on a simple $\mathcal{L}$-module $V$, then $V$ must be restricted.
