自内射代数和Artin-Schelter正则代数的返回箭头
Returning Arrows for Self-injective Algebras and Artin-Schelter Regular Algebras
摘要：
本文讨论了在构造扩张时，一些重要代数箭图中出现的关于Nakayama平移的返回箭头。在构造分次自内射代数的扭曲平凡扩张时，我们证明了返回箭头出现在图中，在Koszul情形下复杂度增加1，在一定的附加条件下表示维数也增加1.利用Koszul对偶，对每一个整体维数为1且Gelfand-Kirilov维数为$c$的Koszul Artin-Schelter正则代数，构造了一族整体维数为$l+1$且Gelfand-Kirilov维数为$c+1$的Koszul Artin-Schelter正则代数，其中一个是中心扩张，另一个是$l+1$ -Calabi-Yau.
英文摘要：
In this paper, we discuss returning arrows with respect to the Nakayama translation appearing in the quivers of some important algebras when we construct extensions. When constructing twisted trivial extensions for a graded self-injective algebra, we show that the returning arrows appear in the quiver, that the complexity increases by 1 in Koszul cases, and the representation dimension also increases by 1 under certain additional conditions. By applying Koszul duality, for each Koszul Artin-Schelter regular algebra of global dimension l and Gelfand-Kirilov dimension $c$, we construct a family of Koszul Artin-Schelter regular algebras of global dimension $l+1$ and Gelfand-Kirilov dimension $c+1$, among them one is central extension and one is $l+1$-Calabi-Yau.
