摘要：
The intermediate coverings of cluster-tilted algebras are constructed from the repetitive cluster categories which are defined in this article. These repetitive cluster categories are Calabi-Yau triangulated categories with fractional CY-dimension and have also cluster tilting objects. Furthermore, we show that the representations of these intermediate coverings of cluster-tilted algebras are induced from the repetitive cluster categories.
