Nef vector bundles on a quadric surface with the first Chern class (2, 1)

Masahiro Ohno
From the journal Advances in Geometry


We classify nef vector bundles on a smooth quadric surface with the first Chern class (2, 1) over an algebraically closed field of characteristic zero; we see in particular that such nef bundles are globally generated.


Deep appreciation goes to the referee for his valuable comments.
