李代数上的LR-结构?双线性乘积是在?,满足一定的交换性关系,并且与李积相容。LR-结构出现在李群上的简单传递仿射作用的研究中。特别是一个感兴趣的问题,李代数承认一个完整的LR结构。本文证明了一个李代数允许一个完备LR-结构当且仅当它允许任何LR-结构。
Abstract An LR-structure on a Lie algebra ? is a bilinear product on ?, satisfying certain commutativity relations, and which is compatible with the Lie product. LR-structures arise in the study of simply transitive affine actions on Lie groups. In particular one is interested in the question which Lie algebras admit a complete LR-structure. In this paper we show that a Lie algebra admits a complete LR-structure if and only if it admits any LR-structure.
