John Wiley & Sons, 1989. Trade paperback of Primes of the Form x^2+ny^2: Fermat, Class Field Theory, and Complex Multiplication by David A. Cox -- a volume in pure and applied mathematics Wiley-Interscience series of texts, monographs, and tracts.
While most texts concentrate on only the elementary or advanced aspects of this story, this book begins with Fermat and explains how his work ultimately gave birth to quadratic reciprocity and the genus theory of quadratic forms.
Very Good. Crisp copy with sturdy binding, clean pages & light shelf wear. Isolated crease to the back cover lower left corner.
