Automorphisms of odd dimensional $(2, 2)$ -complete intersections in characteristic $2$

arXiv:2601.04109

Abstract

We compute the automorphism scheme of a generic odd dimensional $(2, 2)$ -complete intersection in characteristic $2$ . This is the only case for complete intersections having a non-trivial identity component in automorphism schemes apart from quadric hypersurfaces and genus $1$ curves.
