题目: Singularity categories of the cluster-tilted algebras of finite type

摘要: We use the stable categories of some sel_njective algebras to describe the singularity ategories of the cluster-tilted algebras of Dynkin type. Furthermore, in this way, we settle the problem of singularity equivalence classification of the cluster-tilted algebra of type A, D and E,respectively. As a generalization of the structure of the cluster-tilted algebra of type A, we define the gluing Nakayama algebra, and use technique of recollement to describe its singularity category clearly.
