Squares

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.
