5维Artin-Schelter正则代数

Artin-Schelter regular algebras of dimension five

Gunnar Floystad, Jon Eivind Vatne

摘要:

证明了具有两个生成元的5维Artin-Schelter正则代数的Hilbert级数有三种类型。其中一种情况(最极端的情况)可能无法通过分次李代数的包络代数来实现。这是一个新的现象相比,较低的维度,其中所有的分辨率类型可以实现这样的包络代数。

英文摘要:

We show that there are exactly three types of Hilbert series of Artin-Schelter regular algebras of dimension five with two generators. One of these cases (the most extreme) may not be realized by an enveloping algebra of a graded Lie algebra. This is a new phenomenon compared to lower dimensions, where all resolution types may be realized by such enveloping algebras.
