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