Let d>1 be an integer and H be a finite dimensional hereditary algebra over an algebraically closed filed k.Let mod H be the category of finitely generated right H-modules and Db?mod H?be the bounded dereived category with the suspension functor[1].Higher cluster categories?or d-cluster categories?are natural generalization of cluster categories which are defined as the orbit categoriesC=Db?mod H?/?-1[d],where?is the Auslander-Reiten translation on Db?mod H?.In this thesis,we investigate the relative d-rigid subcategories based on higher cluster tilting theory.Our main results show that in a higher cluster category,the relative d-rigid subcategories with respect to a given d-rigid subcategory coincide with rigid subcategories. |
