Specifically, a homological ring epimorphism can induce a lifting of the recollement of the stable category of finitely generated Gorenstein-projective modules; the recollement of the bounded Gorenstein derived categories of some upper triangular matrix algebras can be lifted to the homotopy category of Gorenstein-projective modules. As a byproduct, we give a sufficient and necessary condition on the upper triangular matrix algebra T_{n}(A) to be of finite CM-type for an algebra A of finite CM-type.", "revisions": [ { "version": "v1", "updated": "2022-09-01T15:39:02.000Z" } ], "analyses": { "subjects": [ "18G20", "16G10" ], "keywords": [ "gorenstein projective modules", "upper triangular matrix algebra", "recollement", "gorenstein-projective modules", "finite cm-type" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
