Poincare-Birkhoff-Witt定理的量子模拟

A quantum analog of the Poincare-Birkhoff-Witt theorem

Vladislav Kharchenko

摘要:

我们减少的基础作图题的霍普夫代数产生的斜本原半不变量的特殊元素的研究,称为"超级字母“,这是定义的Shirshov标准字。通过这种方式,我们证明了上述霍普夫代数总是有PBW生成元集(“硬”超级字母)。它还表明,这些霍普夫代数不超过1000个“硬”超字母共享的泛包络代数的有限维李代数的一些性质。证明的背景是一个过滤的建设,使相关的分次代数是通过迭代的斜多项式建设,可能其次是因式分解。

英文摘要:

We reduce the basis construction problem for Hopf algebras generated by skew-primitive semi-invariants to a study of special elements, called ``super-letters,'' which are defined by Shirshov standard words. In this way we show that above Hopf algebras always have sets of PBW-generators (``hard'' super-letters). It is shown also that these Hopf algebras having not more than finitely many ``hard'' super-letters share some of the properties of universal enveloping algebras of finite-dimensional Lie algebras. The background for the proofs is the construction of a filtration such that the associated graded algebra is obtained by iterating the skew polynomials construction, possibly followed with factorization.
