Squares - 171

Many classical and modern results and quadratic forms are brought together in this book.

The treatment is self-contained and of a totally elementary nature requiring only a basic knowledge of rings, fields, polynomials, and matrices, such that the works of Pfister, Hilbert, Hurwitz and others are easily accessible to non-experts and undergraduates alike.

The author deals with many different approaches to the study of squares; from the classical works of the late 19th century, to areas of current research.

Anyone with an interest in algebra or number theory will find this a most fascinating volume.
