群环、包络代数和Poisson代数中的恒等式

Identities in group rings, enveloping algebras and Poisson algebras

Victor Petrogradsky

摘要:

这是一个简短的调查工作相同的关系,在群环,包络代数,泊松对称代数和其他相关的代数结构。首先,Passman的经典工作指定群环满足非平凡的恒等关系。这一结果是密切研究项目的起源和动机。其次,Latyshev和Bahturin确定了李代数,使得它们的泛包络代数满足非平凡恒等关系。接下来,Passman和Petrogradsky解决了限制包络代数的类似问题。第三,法卡斯开始研究泊松代数中的恒等关系。另一方面,Shestakov证明了任意李代数$L$的对称代数$S(L)$满足恒等式$\{x,\{y,z\}\}\equiv 0$当且仅当$L$是交换的。本文综述了李代数的(截断)Poisson对称代数中恒等关系存在性的进一步结果。特别是,我们报告最近的结果(强)李幂零性和(强)可解性(截断)泊松对称代数和相关的幂零类。此外,我们还讨论了实现这些结果的结构和方法。

英文摘要:

This is a short survey of works on identical relations in group rings, enveloping algebras, Poisson symmetric algebras and other related algebraic structures. First, the classical work of Passman specified group rings that satisfy nontrivial identical relations. This result was an origin and motivation of close research projects. Second, Latyshev and Bahturin determined Lie algebras such that their universal enveloping algebra satisfies a non-trivial identical relation. Next, Passman and Petrogradsky solved a similar problem in case of restricted enveloping algebras. Third, Farkas started to study identical relations in Poisson algebras. On the other hand, Shestakov proved that the symmetric algebra $S(L)$ of an arbitrary Lie algebra $L$ satisfies the identity $\{x,\{y,z\}\}\equiv 0$ if, and only if, $L$ is abelian. We survey further results on existence of identical relations in (truncated) Poisson symmetric algebras of Lie algebras. In particular, we report on recent results on (strong) Lie nilpotency and (strong) solvability of (truncated) Poisson symmetric algebras and related nilpotency classes. Also, we discuss constructions and methods to achieve these results.
