一类广义Weyl代数的自同构群

The Automorphism Groups for a family of Generalized Weyl Algebras

Xin Tang

摘要:

本文研究了一类广义Weyl代数$\{\A\}$及其多项式扩张.我们将证明当$p$和$q$都不是单位根时,代数$\A$有单局部化$\A_{\mathbb{S}}$.作为应用,我们确定了$\A$的所有高1素理想和中心,并证明了$\A$是可消的.然后在$p$和$q$都不是单位根的情况下,确定广义Weyl代数$\A$及其多项式扩张的自同构群,并解决它们的同构问题.我们将建立一个量子模拟的Dixlane猜想和计算的自同构群的简单本地化$(\mathcal{A}_{p}(1, 1, \K_{q}[s, t]))_{\mathbb{S}}$。此外,当$p\neq 1$和$q\neq 1$是代数时,我们将完全确定代数$\mathcal{A}_{p}(1, 1, \K_{q}[s, t])$的自同构群及其多项式扩张.

英文摘要:

In this paper, we study a family of generalized Weyl algebras $\{\A\}$ and their polynomial extensions. We will show that the algebra $\A$ has a simple localization $\A_{\mathbb{S}}$ when none of $p$ and $q$ is a root of unity. As an application, we determine all the height-one prime ideals and the center for $\A$, and prove that $\A$ is cancellative. Then we will determine the automorphism group and solve the isomorphism problem for the generalized Weyl algebras $\A$ and their polynomial extensions in the case where none of $p$ and $q$ is a root of unity. We will establish a quantum analogue of the Dixmier conjecture and compute the automorphism group for the simple localization $(\mathcal{A}_{p}(1, 1, \K_{q}[s, t]))_{\mathbb{S}}$. Moreover, we will completely determine the automorphism group for the algebra $\mathcal{A}_{p}(1, 1, \K_{q}[s, t])$ and its polynomial extension when $p\neq 1$ and $q\neq 1$.
