1. Elementos rigidos, valorizações e estrutura de aneis de Witt / Rigid elements, valuations and structure of Witt rings
An ordered field is an algebraic structure like the field of real numbers. However, while the field of real numbers have only one ordering, an arbitrary ordered field F may have more than one ordering, and also a infinite and uncountble number of orderings is allowed. To each element x Î F one can associate an binary quadratic form [1, x], called Pfister 1-
