Criteria for very ampleness of rank two vector bundles over ruled surfaces
Alberto Alzati, GianMario Besana
Very ampleness criteria for rank 2 vector bundles over smooth, ruled surfaces over rational and elliptic curves are given. The criteria are then used to settle open existence quest…

An explicit construction of ruled surfaces
Alberto Alzati, Fabio Tonoli
The main goal of this paper is to give a general method to compute (via computer algebra systems) an explicit set of generators of the ideals of the projective embeddings of some r…

Monomial invariants in codimension two
A. Alzati, A. Tortora
We define the monomial invariants of a projective variety ; they are invariants coming from the generic initial ideal of . Using this notion, we generalize a result of Cook:…
