摘要:

??是丛管子,T??中的极大刚性对象,AT对应的自同态代数,由函子Hom??(T,-)诱导的??的某个满子范畴的商范畴等价于有限生成A-模范畴,基于此,通过??中的对象刻画了A的不可分解刚性模,并给出一个当且仅当的条件。

关键词: 丛管子极大刚性对象刚性模    
Abstract:

Let ?? be a cluster tube,T be a maximal rigid object of ??,A be the endomorphism algebra of T. Hom??(T,-) induces an equivalence between some quotient category and the category of finitely generated A-modules. This note uses this equivalence to characterize the indecomposable rigid modules over A,and gives an if and only if condition for this indecomposable rigid modules.

Key words: cluster tube    maximal rigid object    rigid module
