In this paper we compute the center of many noncommutative algebras that can be interpreted as skew [Formula: see text] extensions. We show that, under some natural assumptions on the parameters that define the extension, either the center is trivial, or, it is of polynomial type. As an application, we provided new examples of noncommutative algebras that are cancellative.

偏斜中心 PBW 扩展

在本文中,我们计算了许多非交换代数的中心,这些代数可以解释为偏斜 [公式:见文本] 扩展。我们表明,在定义扩展的参数的一些自然假设下,中心要么是微不足道的,要么是多项式类型的。作为一个应用程序,我们提供了可抵消的非交换代数的新示例。
