Roberto Aravire and Ricardo Baeza: Annihilators of quadratic and bilinear Pfister forms over fields of characteristic two,

Submission: 2005, Jan 18

Let F be a field of characteristic two. We compute annihilators of bilinear and quadratic Pfisterforms in the graded Witt ring and Witt module of F, thereby confirming in the case of fields with characteristic two certain conjectures estated by Krueskemper.
