K3 of truncated polynomial rings over fields of characteristic two
Janet Aisbett, Victor Snaith · Mathematical Proceedings of the Cambridge Philosophical Society · 1987
Write F for the finite field, , having 2m elements. Let W2(F) denote the Witt vectors of length two over F (for a definition, see [4] or [10], §10). Write F(q) for the truncated polynomial ring, F[t]/(tq).
