C. A. Cremonini, P. A. Grassi

AI总结:

本文研究了李超代数在广义复形式下的上同调,利用谱序列技术计算 Chevalley-Eilenberg 上同调,发现伪形式中存在新的上同调类,扩展了 Koszul 定理与 Poincare 对偶,并为超 p-膜与超引力提供了新视角。

摘要:

我们研究李超代数的上同调(上闭链),针对广义复形式:超形式、伪形式和积分形式。我们认为这些上闭链可以在新的膜扫描的视角下被解释为新高阶 WZW 项的生成元,并可能为超引力提供新来源。我们使用谱序列技术抽象地计算 Chevalley-Eilenberg 上同调。我们首先聚焦于超代数 osp(2|2),并证明在与子超代数相关的伪形式之间存在非空的上同调空间。然后,我们将 Koszul 的一些经典定理扩展到包含伪形式和积分形式。此外,我们推测 Poincare 对偶可以扩展到李超代数,只要考虑所有形式复形,并且我们证明这对于 osp(2|2) 成立。最后,我们通过使用伪形式和积分形式的分布实现,显式地构造了上同调代表元。一方面,这些结果表明李超代数的上同调比预期的更大;另一方面,我们展示了由伪形式表示的全新上同调类的出现。这些类代表子超结构的积分形式类。

英文摘要:

We study the cohomology (cocycles) of Lie superalgebras for the generalised complex of forms: superforms, pseudoforms and integral forms. We argue that these cocycles might be interpreted in the light of a new brane scan as generators of new higher-WZW terms and might provide new sources for supergravity. We use the technique of spectral sequences to abstractly compute the Chevalley-Eilenberg cohomology. We first focus on the superalgebra osp(2|2) and show that there exist non-empty cohomology spaces among pseudoforms related to sub-superalgebras. We then extend some classical theorems by Koszul to include pseudoforms and integral forms. Further, we conjecture that the Poincare' duality extends to Lie superalgebras, as long as all the complexes of forms are taken into account and we prove that this holds for osp}(2|2). We finally construct the cohomology representatives explicitly by using a distributional realisation of pseudoforms and integral forms. On one hand, these results show that the cohomology of Lie superalgebras is larger than expected; on the other hand, we show the emergence of completely new cohomology classes represented by pseudoforms. These classes represent integral form classes of sub-superstructures.
