The theorem claims that for certain triangulated categories with finitely many indecomposable objects, the Calabi-Yau dimension can be computed combinatorially, by finding the smallest d for which the Serre functor and the d'th power of the suspension functor have the same action on the Auslander-Reiten quiver. This is false, and we are grateful to Alex Dugas for pointing out a counterexample; see Section 5 of his paper arXiv:math/0808.1311 for more details. Unfortunately, we are not presently able to come up with a corrected version of the theorem, and this means that we cannot compute the Calabi-Yau dimensions of concrete stable module categories. Since these dimensions are necessary for identifying the categories with higher cluster categories, we presently have no means to achieve such identifications.", "revisions": [ { "version": "v3", "updated": "2010-02-19T13:43:48.000Z" } ], "analyses": { "subjects": [ "16G10", "18E30", "05E99", "16D50", "16G60", "16G70" ], "keywords": [ "stable calabi-yau dimensions", "selfinjective algebras", "concrete stable module categories", "higher cluster categories", "theorem claims" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math.....12451H" } } }
