在非交换不变量理论的背景下,建立了Knörrer周期性定理的一个版本。即设A为左诺瑟A正则代数,设f为A的正次正规元,取B= A/(f)。然后在B上不可分解的非自由极大Cohen-Macaulay模的同构类集与它的第二个双分支覆盖(b#)#上的同构类集(一个非交换类比)之间存在一个双射。我们的结果利用并扩展了前三位作者与Cassidy一起介绍的扭曲矩阵分解的研究。这些结果应用于第二和第四作者与Chan和Zhang研究的非交换Kleinian奇异点。
We establish a version of Knörrer's Periodicity Theorem in the context of noncommutative invariant theory. Namely, let A be a left noetherian AS-regular algebra, let f be a normal and regular element of A of positive degree, and take B= A/(f). Then there exists a bijection between the set of isomorphism classes of indecomposable non-free maximal Cohen-Macaulay modules over B and those over (a noncommutative analog of) its second double branched cover (B#)#. Our results use and extend the study of twisted matrix factorizations, which was introduced by the first three authors with Cassidy. These results are applied to the noncommutative Kleinian singularities studied by the second and fourth authors with Chan and Zhang.
