商奇点的倾斜和簇倾斜

Tilting and cluster tilting for quotient singularities

Osamu Iyama, Ryo Takahashi

摘要:

我们将证明商奇点上分次Cohen-Macaulay模的稳定范畴具有倾斜对象。特别地,这些范畴是三角形等价于有限维代数的导出范畴。我们的方法是基于高维Auslander-Reiten理论,它给出了集群倾斜对象的稳定范畴(未分次)Cohen-Macaulay模块。

英文摘要:

We shall show that the stable categories of graded Cohen-Macaulay modules over quotient singularities have tilting objects. In particular, these categories are triangle equivalent to derived categories of finite dimensional algebras. Our method is based on higher dimensional Auslander-Reiten theory, which gives cluster tilting objects in the stable categories of (ungraded) Cohen-Macaulay modules.
