对称群的扭群代数在自由结合复代数权子空间上的表示

A representation of twisted group algebra of symmetric groups on weight subspaces of free associative complex algebra

Milena Sosic

摘要:

在这里,我们考虑两个代数,一个自由酉结合复代数(表示为${\mathcal{B}}$)配备了多参数\textbf{\emph{q}} -微分结构和扭曲群代数(表示为${\mathcal{A}(S_{n})}$),与动机表示代数${\mathcal{A}(S_{n})}$上的(通用)的重量子空间的代数${\mathcal{B}}$。在${\mathcal{B}}$中的一个基本问题是描述所有常数的空间(被所有多参数偏导数湮没的元素)。为了解决这个问题,需要一些特殊的矩阵和它们的简单矩阵分解。一个更简单的方法是首先研究扭群代数${\mathcal{A}(S_{n})}$中的某些标准元。然后可以在${\mathcal{B}}$的权子空间上使用${\mathcal{A}(S_{n})}$的某些自然表示,这是本文的主题。

英文摘要:

Here we consider two algebras, a free unital associative complex algebra (denoted by ${\mathcal{B}}$) equiped with a multiparametric \textbf{\emph{q}}-differential structure and a twisted group algebra (denoted by ${\mathcal{A}(S_{n})}$), with the motivation to represent the algebra ${\mathcal{A}(S_{n})}$ on the (generic) weight subpaces of the algebra ${\mathcal{B}}$. One of the fundamental problems in ${\mathcal{B}}$ is to describe the space of all constants (the elements which are annihilated by all multiparametric partial derivatives). To solve this problem, one needs some special matrices and their factorizations in terms of simpler matrices. A simpler approach is to study first certain canonical elements in the twisted group algebra ${\mathcal{A}(S_{n})}$. Then one can use certain natural representation of ${\mathcal{A}(S_{n})}$ on the weight subspaces of ${\mathcal{B}}$, which are the subject of this paper.
