We give a description of the singularity category of $A$ inside its stable module category. We prove that there is a duality between the singularity category of $A$ and the singularity category of its opposite algebra. As a consequence, the resolution quiver of $A$ and the resolution quiver of its opposite algebra have the same number of cycles and the same number of cyclic vertices.", "revisions": [ { "version": "v1", "updated": "2014-04-09T12:00:24.000Z" } ], "analyses": { "subjects": [ "16G10", "16D90", "18E30" ], "keywords": [ "singularity category", "nakayama algebra", "opposite algebra", "resolution quiver", "stable module category" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1404.2451S" } } }
