Harish-Chandra modules for map and affine Lie superalgebras

Lucas Calixto, Vyacheslav Futorny, Henrique Rocha

AI总结:

本文分类了基本经典映射超代数上具有有限权重的单模,证明其由尖点有界模抛物诱导且同构于赋值模,并将结果推广到仿射 Kac-Moody 李超代数,构造零级有界单模并给出分类猜想。

摘要:

我们得到了基本经典映射超代数上具有有限权重的单模分类。任何这样的模都是由一个尖点映射超代数上的单尖点有界模抛物诱导得到的。进一步地,任何单尖点有界模都同构于一个赋值模。作为应用,我们得到了基本经典圈超代数的所有单 Harish-Chandra 模的分类。将这些结果推广到通过添加次数导子得到的仿射 Kac-Moody 李超代数,我们构造了一族零级有界单模,并猜想所有有界单尖点模都属于这一族。最后,我们证明对于 I 型仿射 Kac-Moody 李超代数,Kac 诱导函子将所有单有界模的分类归结为其偶部上同一类模的分类,而该类模的分类已由 Dimitrov 和 Grantcharov 给出。

英文摘要:

We obtain a classification of simple modules with finite weight multiplicities over basic classical map superalgebras. Any such module is parabolic induced from a simple cuspidal bounded module over a cuspidal map superalgebra. Further on, any simple cuspidal bounded module is isomorphic to an evaluation module. As an application, we obtain a classification of all simple Harish-Chandra modules for basic classical loop superalgebras. Extending these results to affine Kac-Moody Lie superalgebras obtained by adding the degree derivation, we construct a family of bounded simple modules of level zero, and conjecture that all bounded simple cuspidal modules belong to this family. Finally, we show that for affine Kac-Moody Lie superalgebras of type I the Kac induction functor reduces the classification of all simple bounded modules to the classification of the same class of modules over the even part, whose classification is claimed by Dimitrov and Grantcharov.
