This book contains the proceedings of the Seminar on Quadratic and Hermitian Forms held at McMaster University, July Between andmost of the work in quadratic (and hermitian) forms took place in arithmetic theory (M.

Eichler, M. Kneser, O. O'Meara). In the mid-sixties, the algebraic theory of quadratic forms experienced a reawakening with the fundamental discoveries of. For a long time - at least from Fermat to Minkowski - the theory of quadratic forms was a part of number theory. Much of the best work of the great number theorists of the eighteenth and nineteenth century was concerned with problems about quadratic forms.

On the basis of their work, Minkowski, Siegel, Hasse, Eichler and many others crea ted the impressive "arithmetic" theory of quadratic. We prove first that, for fixed integers n, m⩾1, there is a uniform bound on the number of Pfister forms of degree n over any Pythagorean field F necessary to represent (in the Witt ring of F) any form of dimension m as a linear combination of such forms with non-zero coefficients in F.

“Uniform” means that the bound does not depend either on the form or on the field F; it is given by a. Marshall's abstract theory of spaces of orderings is a powerful tool in the algebraic theory of quadratic forms.

We develop an abstract theory for semiorderings, developing a notion of a space of. The book emphasizes the close connections and interplay between valuations and orderings, and to a large extent, studies them in a unified manner.

The presentation is almost entirely self-contained. In particular, the text develops the needed machinery of ordered abelian groups. Lam, T.
