关于有理扭广义Weyl代数

On rational twisted generalized Weyl algebra

Natalia Golovashchuk, João Schwarz

摘要:

本文研究了当系数环是特征零域上多项式环的局部化,并给出对合时,扭代数的结构.给出了有理扭广义Weyl代数的一个并行构造.基于复李代数的泛包络代数的Gelfand-Zeitlin实现,给出了构造性描述这些代数及其对合对称不变子代数的方法和公式.作为具体的例子,我们讨论特殊的酉和正交代数的秩三。

英文摘要:

The aim of this work is to investigate the structure of some skew twisted algebras, when the coefficient ring is a localization of the polynomial ring over the field of characteristic zero, and an involution is provided. A parallel construction of the rational twisted generalized Weyl algebras is given. We propose a method and explicit formulas for a constructive description of these algebras and their involution-symmetric invariant subalgebras based on the Gelfand-Zeitlin realization of the universal enveloping algebra of some complex Lie algebras. As concrete examples we discuss special unitary and orthogonal algebras of rank three.
