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…

Mutating loops and 2-cycles in 2-CY triangulated categories
Marco Angel Bertani-Økland, Steffen Oppermann
We derive an algorithm for mutating quivers of 2-CY tilted algebras that have loops and 2-cycles, under certain specific conditions. Further, we give the classification of the 2-CY…

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.
