Globally generated vector bundles on a smooth quadric threefold
Abstract : Globally generated vector bundles are basic objects in projective algebraic geometry and they correspond to morphisms to Grassmannian varieties. Recently there have been several works on the classification of globally generated vector bundles on projective spaces. In this talk, we classify globally generated vector bundles with very low first Chern class on a smooth quadric threefold, starting with the rank 2 case to even higher rank. And we also investigate their indecomposability. Main ingredients are the Liaison and the technique of smoothing algebraic curves on a quadric threefold.
This is joint work with E. Ballico and F. Malaspina.
