Under some mild genericity condition, we prove that parabolic induction with respect to a parabolic subgroup $P=LN$ defines an isomorphism between the universal deformation rings of a supersingular representation $\\bar{\\sigma}$ of $L$ and of its parabolic induction $\\bar{\\pi}$. As a consequence, we show that every Banach lift of $\\bar{\\pi}$ is induced from a unique Banach lift of $\\bar{\\sigma}$.", "revisions": [ { "version": "v1", "updated": "2016-07-09T12:02:18.000Z" } ], "analyses": { "subjects": [ "22E50" ], "keywords": [ "parabolic induction", "universal deformation rings", "unique banach lift", "mild genericity condition", "study deformations" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
