Abstract

In this paper, we will prove that any \A3\A^3-form over a field kk of characteristic zero is trivial provided it has a locally nilpotent derivation satisfying certain properties. We will also show that the result of T. Kambayashi on the triviality of separable \A2\A^2-forms over a field kk extends to \A2\A^2-forms over any one-dimensional Noetherian domain containing \bQ\bQ.
