关于项链李代数的结构 总被引:2,自引:0,他引:2
Le Bruyn和V.Ginzbrug最近引入了项链李代数。它是定义在箭图上的一种无限堆李代数,在非交换几何研究中起了重要作用。本研究项链李代数结构,证明了当箭图中有长度大于1的循环时,其项链李代数不是幂零李代数,我们还给出了没有圈的箭图上项链李代数的分解。 相似文献

小特征的有限维Cartan型李代数的滤过 总被引:1,自引:0,他引:1
张永正 《数学年刊A辑(中文版)》1995,(6)
用L表示Cartan型李代数W(n,m),S(n,m)或H(n,m〕.本文证明了当基域F的特征数p=2与3时L的自然滤过是不变的.从而得到了当p=2与3时,L的每个自同构都是由与之相应的除幂代数的自同构所诱导的. 相似文献

A-扩张Lie Rinehart代数 总被引:1,自引:0,他引:1
The purpose of this paper is to give a brief introduction to the category of Lie Rinehart algebras and introduces the concept of smooth manifolds associated with a unitary, commutative,associative algebra A.It especially shows that the A-extended algebra as well as the action algebra can be realized as the space of A-left invariant vector fields on a Lie group,analogous to the well known relationship of Lie algebras and Lie groups. 相似文献

A Lie module algebra for a Lie algebra L is an algebra and L-module A such that L acts on A by derivations. The depth Lie algebra of a Lie algebra L with Lie module algebra A acts on a corresponding depth Lie module algebra . This determines a depth functor from the category of Lie module algebra pairs to itself. Remarkably, this functor preserves central simplicity. It follows
that the Lie algebras corresponding to faithful central simple Lie module algebra pairs (A,L) with A commutative are simple. Upon iteration at such (A,L), the Lie algebras are simple for all i ∈ ω. In particular, the (i ∈ ω) corresponding to central simple Jordan Lie algops (A,L) are simple Lie algebras.

Novikov algebras and Novikov structures on Lie algebras 总被引:1,自引:0,他引:1
We study ideals of Novikov algebras and Novikov structures on finite-dimensional Lie algebras. We present the first example of a three-step nilpotent Lie algebra which does not admit a Novikov structure. On the other hand we show that any free three-step nilpotent Lie algebra admits a Novikov structure. We study the existence question also for Lie algebras of triangular matrices. Finally we show that there are families of Lie algebras of arbitrary high solvability class which admit Novikov structures. 相似文献

The ?-grading determined by a long simple root of a rank n+1 a?ne Lie algebra over ? arises from a representation of a rank n semi-simple complex Lie algebra. Analysis of the relationship between the grading and the representation yields constructions that generalize the minuscule and adjoint algorithms as well as Kac’s construction of nontwisted a?ne Lie algebras. 相似文献
