On Exponentiality of Automorphisms of $${\textbf {A}}^{n}$$ of Order p in Characteristic $$p>0$$

Abstract Let X be an integral affine scheme of characteristic $$p>0$$ p > 0 , and $$\sigma $$ σ a non-identity automorphism of X . If $$\sigma $$ σ is exponential , i.e., induced from a $$\textbf{G}_a$$ G a -action on X , then $$\sigma $$ σ is obviously of order p . It is easy to...
