摘要:

从有限维李代数的理论出发,我们知道,每一个有限维李代数都可分解为半单子代数与可解根的半直和。此外,由于工作的Mal'cev的研究可解李代数减少到研究幂零的。对于有限维的Leibniz代数,上述结果的类似结果尚未得到证明。为了得到一些想法如何建立的结果,我们研究的Leibniz代数的商代数关于理想所产生的代数的平方元素(表示为$I$)是一个半直和的半单李代数和极大可解理想。本文描述了一类复Leibniz代数,其中理想$I$的商代数同构于代数$sl_2$与二维可解理想$R$的半直和.

英文摘要:

From the theory of finite dimensional Lie algebras it is known that every finite dimensional Lie algebra is decomposed into a semidirect sum of semisimple subalgebra and solvable radical. Moreover, due to work of Mal'cev the study of solvable Lie algebras is reduced to the study of nilpotent ones. For the finite dimensional Leibniz algebras the analogues of the mentioned results are not proved yet. In order to get some idea how to establish the results we examine the Leibniz algebra for which the quotient algebra with respect to the ideal generated by squares elements of the algebra (denoted by $I$) is a semidirect sum of semisimple Lie algebra and the maximal solvable ideal. In this paper the class of complex Leibniz algebras, for which quotient algebras by the ideal $I$ are isomorphic to the semidirect sum of the algebra $sl_2$ and two-dimensional solvable ideal $R$, are described.
