- Nef vector bundles on a quadric surface with first Chern class (2,2)
Masahiro Ohno
Lead, Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry, Springer Science and Business Media LLC, 18 Apr. 2025, Peer-reviwed, Abstract
We classify nef vector bundles on a smooth quadric surface with first Chern class (2, 2) over an algebraically closed field of characteristic zero.

We classify nef vector bundles on a smooth hyperquadric of dimension three with first Chern class two over an algebraically closed field of characteristic zero. In particular, we see that they are globally generated.
