摘要
本文考察了反李三系和它的标准嵌入李超代数的Killing型之间的关系,并且证明了反李三系的反对称不变双线性型可以被唯一地扩张到它的标准嵌入李超代数。作为扩张定理的一个应用,得到了二次李和反李三系的唯一分解定理。
The authors investigate the relationship between the Killing form of an anti-Lie triple system and that of its standard imbedding Lie superalgebra, and prove that an invariant anti-symmetric bilinear form on an anti-Lie triple system can be uniquely extended to its standard imbedding Lie superalgebra. As an application of the extension theorem, finally, the unique decomposition theorems for the quadratic Lie and anti-Lie triple systems are obtained.
