This exploration of Quadratic Forms over Rational numbers and Rational integers offers an excellent elementary introduction to many aspects of a classical subject, including recent developments.
The author, a Professor Emeritus at Trinity College, University of Cambridge, offers a largely self-contained treatment that develops most of the prerequisites.
Topics include the theory of Quadratic Forms over local fields, Forms with integral coefficients, genera and spinor genera, reduction theory f.
