Extendable codimension two subvarieties in a general hypersurface

Algebraic Geometry 2025-10-10 v1

Abstract

We exhibit a class of extendable codimension 22 subvarieties in a general hypersurface of dimension at least 44 in projective space. As a consequence, we prove that a general hypersurface of degree dd and dimension at least 44 does not support globally generated indecomposable ACM bundles of any rank if their first Chern class ede \ll d.
