We give such a bound in terms of the number of vertices of the underline quiver. Consequently, we get the nilpotency index of the radical of the module category for representation-finite self-injective cluster tilted algebras. We also study the non-zero composition of $m$, $m \\ge 2$, irreducible morphisms between indecomposable modules in representation-finite cluster tilted algebras lying in the $(m+1)$-th power of the radical of their module category.", "revisions": [ { "version": "v1", "updated": "2020-06-23T01:09:24.000Z" } ], "analyses": { "keywords": [ "module category", "cluster tilted algebras lying", "representation-finite cluster tilted algebra vanishes", "th power", "minimal lower bound" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
