We also establish a `hidden' invariance property of Fourier coefficients. We apply these results to minimal and next-to-minimal automorphic representations, and deduce Eulerianity for a large class of Fourier coefficients. In particular, we prove Eulerianity for parabolic Fourier coefficients with characters of maximal rank for a class of Eisenstein series in minimal and next-to-minimal representations of groups of ADE-type that are of interest in string theory.", "revisions": [ { "version": "v1", "updated": "2020-04-29T14:48:33.000Z" } ], "analyses": { "subjects": [ "11F30", "11F70", "22E55", "20G45" ], "keywords": [ "automorphic forms", "parabolic fourier coefficients", "general transfer theorem", "next-to-minimal automorphic representations", "next-to-minimal representations" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
