Isomorphisms and Automorphisms of Witt Rings

Canadian Mathematical Bulletin, 1988
AbstractFor a field F, char(F) ≠ 2, let WF denote the Witt ring of quadratic forms of F and let denote the multiplicative group of 1-dimensional forms It follows from a construction of D. K. Harrison that if E, F are fields (both of characteristic ≠ 2) and ρ.WE → WF is a ring isomorphism, then there exists a ring isomorphism which “preserves ...

Annihilating Polynomials for Group Rings and Witt Rings

Canadian Mathematical Bulletin, 1989
AbstractNatural annihilating polynomials for group rings are produced; this yields, as a special case, the annihilating polynomials for Witt rings that have been discovered only recently.
