Witt kernels and Brauer kernels for quartic extensions in characteristic two

Detlev W. Hoffmann, Marco Sobiech

Let $F$ be a field of characteristic $2$ and let $E / F$ be a field extension of degree $4$ . We determine the kernel $W_{q} (E / F)$ of the restriction map $W_{q} F \to W_{q} E$ between the Witt…

Witt kernels of quadratic forms for multiquadratic extensions in characteristic 2

Detlev W. Hoffmann

Let $F$ be a field of characteristic $2$ and let $K / F$ be a purely inseparable extension of exponent $1$ . We show that the extension is excellent for quadratic forms. Using the exc…
