Bringing the material up to date to reflect modern applications Algebraic Number Theory Second Edition has been completely rewritten and reorganized to incorporate a new style methodology and presentation. This edition focuses on integral domains ideals and unique factorization in the first chapter; field extensions in the second chapter; and class groups in the third chapter. Applications are now collected in chapter four and at the end of chapter five where primality testing is highlighted as an application of the KroneckerâWeber theorem. In chapter five the sections on ideal decomposition in number fields have been more evenly distributed. The final chapter continues to cover reciprocity laws. New to the Second Edition Reorganization of all chapters More complete and involved treatment of Galois theory A study of binary quadratic forms and a comparison of the ideal and form class groups More comprehensive section on Pollardâs cubic factoring algorithm More detailed explanations of proofs with less reliance on exercises to provide a sound understanding of challenging material The book includes mini-biographies of notable mathematicians convenient cross-referencing a comprehensive index and numerous exercises. The appendices present an overview of all the concepts used in the main text an overview of sequences and series the Greek alphabet with English transliteration and a table of Latin phrases and their English equivalents. Suitable for a one-semester course this accessible self-contained text offers broad in-depth coverage of numerous applications. Readers are lead at a measured pace through the topics to enable a clear understanding of the pinnacles of algebraic number theory. . Language: English
