This has been investigated by a number of authors for Dirichlet characters $\\chi$ of a fixed modulus and having the same parity as $k$.The focal point of this article is to extend this investigation to families of Dirichlet characters modulo distinct pairwise co-prime natural numbers. The interplay between the resulting ambient number fields brings in new technical issues and complications hitherto absent in the context of a fixed modulus (consequently a single number field lurking in the background). This entails a very careful and hands-on dealing with the arithmetic of compositum of number fields which we undertake in this work. Our results extend earlier works of the first author with Murty-Rath as well as works of Okada, Murty-Saradha and Hamahata.", "revisions": [ { "version": "v1", "updated": "2022-12-01T08:50:11.000Z" } ], "analyses": { "subjects": [ "11J72", "11R18", "11M06" ], "keywords": [ "linear independence", "ambient number fields brings", "dirichlet characters modulo distinct", "characters modulo distinct pairwise co-prime", "distinct pairwise co-prime natural numbers" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier" }, "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
