Comments are welcome!", "categories": [ "math.RT" ], "abstract": "In this paper, we introduce the notions of Gorenstein projective $\\tau$-rigid modules, Gorenstein projective support $\\tau$-tilting modules and Gorenstein torsion pairs and give a Gorenstein analog to Adachi-Iyama-Reiten's bijection theorem on support $\\tau$-tilting modules. More precisely, for an algebra $\\Lambda$, we show that there is a bijection between the set of Gorenstein projective $\\tau$-rigid pairs in $\\mod \\Lambda$ and the set of Gorenstein injective $\\tau^{-1}$-rigid pairs in $\\mod \\Lambda^{\\rm op}$. We prove that there is a bijection between the set of Gorenstein projective support $\\tau$-tilting modules and the set of functorially finite Gorenstein projective torsion classes. As an application, we introduce the notion of CM-$\\tau$-tilting finite algebras and show that $\\Lambda$ is CM-$\\tau$-tilting finite if and only if $\\Lambda^{\\rm {op}}$ is CM-$\\tau$-tilting finite.", "revisions": [ { "version": "v1", "updated": "2021-09-02T23:49:06.000Z" } ], "analyses": { "subjects": [ "16G10", "18G25" ], "keywords": [ "tilting finite", "tilting modules", "gorenstein projective support", "finite gorenstein projective torsion classes", "rigid pairs" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable" } } }
