簇倾斜代数上由其维数向量决定的模

Modules over cluster-tilted algebras determined by their dimension vectors

Ibrahim Assem, Grégoire Dupont

摘要:

证明了簇倾斜代数上的不可分解的transjective模是由其维数向量唯一确定的。同样地,我们证明了对于簇隐代数,提升到相应簇范畴中刚性对象的刚性模由它们的维数向量唯一确定。最后,我们将我们的结果应用到一个猜想的Fomin和Zelevinsky的集群变量的分解。

英文摘要:

We prove that indecomposable transjective modules over cluster-tilted algebras are uniquely determined by their dimension vectors. Similarly, we prove that for cluster-concealed algebras, rigid modules lifting to rigid objects in the corresponding cluster category are uniquely determined by their dimension vectors. Finally, we apply our results to a conjecture of Fomin and Zelevinsky on denominators of cluster variables.
