摘要
Let A be a hereditary algebra. We construct a fundamental domain for the cluster category CA inside the category of modules over the duplicated algebra A of A. We then prove that there exists a bijection between the tilting objects in CA and the tilting A-modules all of whose nonprojective-injective indecomposable summands lie in the left part of the module category of A.
