Using a suitable process of mutations of quivers with potentials (which are also BB-mutations) inducing derived equivalences, and one-pointed (co)extensions which preserve singularity equivalences, we find a connected selfinjective Nakayama algebra singularity equivalent to each simple polygon-tree algebra. Furthermore, we also give a classification of this kind of algebras up to representation type.", "revisions": [ { "version": "v1", "updated": "2015-09-18T05:54:47.000Z" } ], "analyses": { "keywords": [ "singularity categories", "selfinjective nakayama algebra singularity equivalent", "preserve singularity equivalences", "simple polygon-tree algebra", "connected selfinjective nakayama algebra singularity" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150905511L" } } }
