书目名称 | On the Class Number of Abelian Number Fields | 副标题 | Extended with Tables | 编辑 | Helmut Hasse | 视频video | | 概述 | First English translation of the original German edition.Provides systematic tables on the relative class number of imaginary abelian number fields.Contains rigorous results on the class numbers of ab | 图书封面 |  | 描述 | .With this translation, the classic monograph .Über die Klassenzahl abelscher Zahlkörper. by Helmut Hasse is now available in English for the first time..The book addresses three main topics: class number formulas for abelian number fields; expressions of the class number of real abelian number fields by the index of the subgroup generated by cyclotomic units; and the Hasse unit index of imaginary abelian number fields, the integrality of the relative class number formula, and the class number parity. .Additionally, the book includes reprints of works by Ken-ichi Yoshino and Mikihito Hirabayashi, which extend the tables of Hasse unit indices and the relative class numbers to imaginary abelian number fields with conductor up to 100.. .The text provides systematic and practical methods for deriving class number formulas, determining the unit index and calculating the class number of abelian number fields. A wealth of illustrative examples, together with corrections and remarks on the original work, make this translation a valuable resource for today’s students of and researchers in number theory.. | 出版日期 | Book 2019 | 关键词 | abelian number fields; algebraic number theory; class field theory; class number formula; relative class | 版次 | 1 | doi | https://doi.org/10.1007/978-3-030-01512-1 | isbn_ebook | 978-3-030-01512-1 | copyright | Springer Nature Switzerland AG 2019 |
