ACM bundles on general hypersurfaces in of low degree
L. Chiantini, C. Madonna
In this paper we show that on a general hypersurface of degree in a rank 2 vector bundle splits if and only if for all $n \in \bf…

Halphen conditions and postulation of nodes
L. Chiantini, N. Chiarli, S. Greco
We give sharp lower bounds for the postulation of the nodes of a general plane projection of a smooth connected curve C in P^r and we study the relationships with the geometry of t…

A splitting criterion for rank 2 vector bundles on a general sextic threefold
Luca Chiantini, Carlo Madonna
In this paper we show that on a general sextic hypersurface , a rank 2 vector bundle splits if and only if for any . We get thus a…
