AI总结:

本文构建了受限李三系的低阶上同调理论,定义了直到5阶的受限上链与上边界算子,并阐释了低阶上同调群在导子、模扩张、形式形变及系统扩张中的代数意义。

AI中文摘要:

本文的主要目的是提供受限李三系在低阶的上同调理论及其代数解释。我们定义了直到5阶的受限上链,以及相应的上边界算子。此外,我们给出了低阶受限上同调群在受限导子、受限模的扩张、形式形变以及受限李三系的扩张方面的解释。

英文摘要:

The main purpose of this paper is to provide a cohomology theory of restricted Lie triple systems in low degrees and their algebraic interpretations. We define restricted cochains up to degree 5, together with the corresponding coboundary operators. Moreover, we provide interpretations of the low-degree restricted cohomology groups in terms of restricted derivations, extensions of restricted modules, formal deformations, and extensions of restricted Lie triple systems.
