具有周期模范畴和指数增长的 Jacobian 代数

表示论 2016-03-14 v4

摘要

与带有标记点集合 MM 的闭曲面 SS 的三角剖分相关联的 Jacobian 代数是(弱)对称且驯化的。我们证明,对于这些代数,Auslander-Reiten 平移在对象上表现为 2-周期性。此外,我们证明除了球面带有 4 个(或更少)穿孔的情况外,这些代数均具有指数增长性。这四个性质表明存在一类新的代数族,它们是对称的、驯化的且具有周期模范畴。作为 Auslander-Reiten 平移在对象上 2-周期性作用的结果,广义团簇范畴 \cC(S,M)\cC_{(S,M)} 的 Auslander-Reiten 箭图仅由秩为 1 或 2 的稳定管组成。

备注

In the previous version I showed that the Jacobian algebras of closed surfaces, excluding the case of the sphere with 4 and 5 punctures, are algebras of exponential growth and it was changed grammar errors. In this new version I change the name of this note and I show that the Jacobian algebras of the sphere with 5 punctures are algebras of exponential growth. This is the final version
