Quadratic forms, orderings and quaternion algebras over rings with many units
The "algebraic" theory of quadratic forms over fields of characteristic ≠2 dates back to the 1937 paper of Witt [37]. It was in this paper that the Witt ring of a field was first considered. Thirty years later, Pfister published his work on the structure of the Witt ring [31]-[33]. Thes...
