Cohomological Characterization of Vector Bundles on Grassmannians of Lines
Enrique Arrondo, Francesco Malaspina
We introduce a notion of regularity for coherent sheaves on Grassmannians of lines. We use this notion to prove some extension of Evans-Griffith criterion to characterize direct su…

Qregularity and tensor products of vector bundles on smooth quadric hypersurfaces
Edoardo Ballico, Francesco Malaspina
Let $\Q_n \subset \mathbb P^{n+1}$ be a smooth quadric hypersurface. Here we prove that the tensor product of an -Qregular sheaf on $\Q_n$ and an -Qregular vector bundle on $…
