我们引入一类新的代数,我们称之为集群倾斜代数。它们是定义在一个簇范畴中倾斜对象的自同态代数。我们表明,他们的表示理论是非常接近的遗传代数的表示理论。作为一个应用程序,我们证明了一个广义版本的所谓的APR倾斜。
We introduce a new class of algebras, which we call cluster-tilted. They are by definition the endomorphism algebras of tilting objects in a cluster category. We show that their representation theory is very close to the representation theory of hereditary algebras. As an application of this, we prove a generalised version of so-called APR-tilting.
