Witt kernels of function field extensions in characteristic 2

Abstract

In characteristic 2 we give a complete characterization of anisotropic symmetric bilinear forms that become metabolic over the function field of a quadratic form. We also study the hyperbolicity of nonsingular quadratic forms over such a field by generalizing some results by Fitzgerald [6]. As an application, we introduce and study the notion of Pfister… (More)
