On automorphism groups of smooth hypersurfaces

Algebraic Geometry 2025-01-30 v2

Abstract

We show that smooth hypersurfaces in complex projective spaces with automorphism groups of maximum size are isomorphic to Fermat hypersurfaces, with a few exceptions. For the exceptions, we give explicitly the defining equations and automorphism groups.
