扭曲Weyl代数、交叉积和表示

Twisted Weyl algebras, crossed products, and representations

Vyacheslav Futorny, Jonas T. Hartwig

摘要:

证明了任意满足一定相容性条件的扭曲广义Weyl代数都可以嵌入到交叉积中。我们还介绍了一个新的家庭扭曲的广义Weyl代数,称为多参数扭曲的Weyl代数,我们参数化的某一种的所有简单的等价物。Jordan的多参数量子化Weyl代数的简单局部化和Hayashi的$q$ -类似的Weyl代数都是这种构造的特例。我们对任意多参数扭Weyl代数上的单权模进行了分类。推广Benkart和Ondrus的结果,我们还描述了一类扭曲广义Weyl代数上的所有Whittaker对同构,其中包括多参数扭曲Weyl代数.

英文摘要:

We prove that any twisted generalized Weyl algebra satisfying certain consistency conditions can be embedded into a crossed product. We also introduce a new family of twisted generalized Weyl algebras, called multiparameter twisted Weyl algebras, for which we parametrize all simple quotients of a certain kind. Both Jordan's simple localization of the multiparameter quantized Weyl algebra and Hayashi's $q$-analog of the Weyl algebra are special cases of this construction. We classify all simple weight modules over any multiparameter twisted Weyl algebra. Extending results by Benkart and Ondrus, we also describe all Whittaker pairs up to isomorphism over a class of twisted generalized Weyl algebras which includes the multiparameter twisted Weyl algebras.
