On Buchsbaum bundles on quadric hypersurfaces
Edoardo Ballico, Francesco Malaspina, Paolo Valabrega +1
Let be an indecomposable rank two vector bundle on the projective space $\PP^n, n \ge 3$, over an algebraically closed field of characteristic zero. It is well known that i…

Non-vanishing theorems for rank 2 bundles on P^3: a simple approach without the speciality lemma
Paolo Valabrega, Mario Valenzano
The paper investigates vanishing conditions on the first cohomology module of a normalized rank 2 vector bundle E on P^3 which force E to split, and finds therefore strategic level…
