Graded mutation in cluster categories coming from hereditary categories with a tilting object
Marco Angel Bertani-Økland, Steffen Oppermann, Anette Wrålsen
We present a graded mutation rule for quivers of cluster-tilted algebras. Furthermore, we give a technique to recover a cluster-tilting object from its graded quiver in the cluster…

Finding a cluster-tilting object for a representation finite cluster-tilted algebra
Marco Angel Bertani-Økland, Steffen Oppermann, Anette Wrålsen
We provide a technique to find a cluster-tilting object having a given cluster-tilted algebra as endomorphism ring in the finite type case.

Rigid objects in higher cluster categories
Anette Wrålsen
We study maximal -rigid objects in the -cluster category associated with a finite dimensional hereditary algebra with nonisomorphic simple modules. W…
