We show that the local Rankin-Selberg root number of any pair of distinguished representation is trivial and as a corollary we obtain an analogue for the global root number of any pair of distinguished cuspidal representations. We further study the extent to which the gamma factor at $1/2$ is trivial for distinguished representations as well as the converse problem.", "revisions": [ { "version": "v1", "updated": "2016-07-07T12:16:59.000Z" } ], "analyses": { "subjects": [ "22E50", "11F70" ], "keywords": [ "gamma factors root numbers", "distinction", "local rankin-selberg root number", "distinguished representation", "general linear group" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
