预投射代数上模空间的倾斜理论方法

Tilting theoretical approach to moduli spaces over preprojective algebras

Yuhi Sekiya, Kota Yamaura

摘要:

利用预投射代数$Lambda$上的倾斜理论研究了$Lambda$ -模的模空间.本文利用$Lambda$上的倾斜模定义了半稳定模的范畴,并给出了它们之间的一个等价,即所谓的反射函子。此外,我们证明了等价性诱导了模空间之间代数簇的同构。特别地,我们研究了当模空间与Kleinian奇点相关时的情形。本文推广了Crawley-Boevey的一个结果,它是Ito-Nakamura型McKay对应的又一证明。

英文摘要:

We apply tilting theory over preprojective algebras $Lambda$ to a study of moduli space of $Lambda$-modules. We define the categories of semistable modules and give an equivalence, so-called reflection functors, between them by using tilting modules over $Lambda$. Moreover we prove that the equivalence induces an isomorphism of algebraic varieties between moduli spaces. In particular, we study in the case when the moduli spaces related to the Kleinian singularity. We generalize a result of Crawley-Boevey which is known another proof of the McKay correspondence of Ito-Nakamura type.
