有限维复丝状Leibniz代数的分类(下)

On Classification of Finite Dimensional Complex Filiform Leibniz Algebras (Part 2)

U. D. Bekbaev, I. S. Rakhimov

摘要:

研究了有限维复非李丝状Leibniz代数的分类问题.实际上,观察表明,有两个资源得到filiform Leibniz代数的分类。第一类是自然分次非李丝状Leibniz代数,第二类是自然分次丝状李代数。利用第一个资源,我们得到了两类不相交的丝状Leibniz代数。本文讨论的是上述两类中的第二类,第一类在我们以前的文章中已经考虑过。这里的代数分类意味着指定轨道的代表,而几何分类是在代数几何意义上寻找通用结构常数的问题。本文的主要工作是代数分类。我们建议在这里的代数方法的基础上不变量。对任何给定的低维情形,利用这种方法都可以对所有的丝状Leibniz代数进行分类。此外,所得结果还可用于这类代数轨道的几何分类。

英文摘要:

The paper is devoted to classification problem of finite dimensional complex none Lie filiform Leibniz algebras. Actually, the observations show there are two resources to get classification of filiform Leibniz algebras. The first of them is naturally graded none Lie filiform Leibniz algebras and the another one is naturally graded filiform Lie algebras. Using the first resource we get two disjoint classes of filiform Leibniz algebras. The present paper deals with the second of the above two classes, the first class has been considered in our previous paper. The algebraic classification here means to specify the representatives of the orbits, whereas the geometric classification is the problem of finding generic structural constants in the sense of algebraic geometry. Our main effort in this paper is the algebraic classification. We suggest here an algebraic method based on invariants. Utilizing this method for any given low dimensional case all filiform Leibniz algebras can be classified. Moreover, the results can be used for geometric classification of orbits of such algebras.
