簇管内极大刚体的自同态代数

Endomorphism algebras of maximal rigid objects in cluster tubes

Dong Yang

摘要:

给定一个簇管的最大刚体$T$,确定由$T$表示的刚体。然后,我们使用凯勒和Reiten的方法表明,自同态代数的$T$是Gorenstein和有限表示型,首先显示的Vatne。当基场的特征不为3时,这个代数就是某个带势的代数的雅可比代数。我们研究了当$T$突变时这种潜在的变化。我们还提供了一个导出的等价分类的自同态代数的极大刚性对象。

英文摘要:

Given a maximal rigid object $T$ of the cluster tube, we determine the objects finitely presented by $T$. We then use the method of Keller and Reiten to show that the endomorphism algebra of $T$ is Gorenstein and of finite representation type, as first shown by Vatne. This algebra turns out to be the Jacobian algebra of a certain quiver with potential, when the characteristic of the base field is not 3. We study how this quiver with potential changes when $T$ is mutated. We also provide a derived equivalence classification for the endomorphism algebras of maximal rigid objects.
