Basic facts about symmetric bilinear forms, and definition of the Witt ring,iled discussion the reader should consult , , , . We will often restrict ourselves to fields with characteristic different from two. Remarks concerning peculiarities of the characteristic two case will be marked by an asterisk.

The structure of Witt rings,f the group ring ℤ, where Q(F) denotes the group F*/F*. of square classes of the field F, we deduce the structure theorems purely ring-theoretically. Thus the results obtained by this way apply to a wider class of rings, which we call “abstract Witt rings”, and not only to Witt rings of symmet

The structure of Witt rings,ric bilinear forms over fields (cf. ). The main theorems about the structure of Witt rings of fields have been proved by Pfister , Leicht-Lorenz and Harrison . Most of the following can be found in a more general setting in .
