Algebraic Number Theory, Second Edition (Discrete Mathematics and its Applications)

This is an introductory text in algebraic number theory that has good coverage ... . This second edition is completely reorganized and rewritten from the first edition. ... Very Good Features: (1) The applications are not limited to Diophantine equations, as in many books, but cover a wide range, including factorization into primes, primality testing, and the higher reciprocity laws. (2) The book has a large number of mini-biographies of the number theorists whose work is being discussed. ...

Praise for the First Edition
This is a remarkable book that will be a valuable reference for many people, including me. The book shows great care in preparation, and the ample details and motivation will be appreciated by lots of students. The solid punches at the end of each chapter will be appreciated by everybody. It deserves success with many adoptions as a text.
