In particular, we describe the construction of an L-group extension of such a covering group (over a split reductive group) due to Weissman, study some of its properties and discuss a variant of it. Using this L-group extension, we describe a local Langlands correspondence for covering (split) tori and unramified genuine representations, using work of Savin, McNamara, Weissman and W.W. Li. Finally, we define the notion of automorphic (partial) L-functions attached to genuine automorphic representations of the BD covering groups.", "revisions": [ { "version": "v1", "updated": "2014-09-14T09:41:11.000Z" } ], "analyses": { "keywords": [ "brylinski-deligne extensions", "langlands-weissman program", "l-group extension", "local langlands correspondence", "genuine automorphic representations" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1409.4039T" } } }
