This is part of the $(\\chi, b)$-theory outlined in [Jia14] and can be regarded as a refinement of the theory of theta correspondences and poles of certain L-functions, which was outlined in [Ral91]. Further studies will be considered in our future work.", "revisions": [ { "version": "v1", "updated": "2014-09-02T15:58:57.000Z" } ], "analyses": { "subjects": [ "11F27", "11F67", "11F70" ], "keywords": [ "unitary group", "simple global arthur parameter", "irreducible cuspidal automorphic representation", "number field", "theta correspondences" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1409.0767J" } } }
