We obtain obstruction spaces for the existence of deformations and also for local deformations to exist globally. Finally we obtain explicit criteria in order for a pure and reduced scheme of finite type over a field $k$ to have smoothings and Q-Gorenstein smoothings.", "revisions": [ { "version": "v2", "updated": "2009-08-24T09:42:33.000Z" } ], "analyses": { "subjects": [ "14D15" ], "keywords": [ "non-isolated singularities", "q-gorenstein deformation theory", "q-gorenstein smoothings", "explicit criteria", "local deformations" ], "note": { "typesetting": "TeX", "pages": 53, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0808.0436T" } } }
