摘要 对于一个cluster-倾斜三元组(D,T,A),讨论了A中的τ-rigid对象与D中的rigid对象之间的关系,并给出了A中的τ-rigid对象可提升到D中的rigid对象的充要条件. Given a cluster-tilting triple (D,J, A),we study the relationship between r-rigid objects in A and rigid objects in D A necessary and sufficient condition is proposed for that a r-rigid object in A can be lifted to a rigid object in D.
