Dis(R) and Qu(R), a domain which is integrally closed in its field of fractions F. In this case, see Section D, separable quadratic algebras can be characterized as the integral closures of R in quadratic Galois extensions of F in which all prime ideals of R are unramified.

Brauer Groups and Witt Groups,s, proofs or sketches of proofs are provided only when they seemed not available in appropriately explicit form. The constructions are presented in the generality of commutative rings and then illustrated in the classical situations: over the real and complex numbers, and local and global fields.

The Arithmetic of Wq(R),tion of Ker . implies that Wq(R) ≅ Cl(R). ⊕ G, where C1(R) is the ideal class group of R and G is a free Abelian group of rank with r the number of real embeddings of the number field. An additional focus is the comparison of the number theory of Wq(R) with that of W(R) and the structure of the quotient W(R)/Wq(R).
