Automorphisms of del Pezzo surfaces of degree 2 in characteristic 2

Abstract

We find normal forms for del Pezzo surfaces of degree $2$ over algebraically closed fields of characteristic $2$. For each normal form, we describe the structure of the group of automorphisms of the surface. In particular, we classify all finite groups that can act on such del Pezzo surfaces.

This is superseded by v2 of arXiv:2209.09082, which combines the two articles
