The dimension of the Hilbert scheme of special threefolds
GianMario Besana, Maria Lucia Fania
The Hilbert scheme of projective 3-folds of codimension 3 or more that are linear scrolls over the projective plane or over a smooth quadric surface or that are quadric or cubic fi…
Peculiar Loci of Ample and Spanned Line Bundles
Gian Mario Besana, Sandra Di Rocco, Antonio Lanteri
The bad locus and the rude locus of an ample and base point free linear system on a smooth complex projective variety are introduced and studied. The bad locus is defined as the se…
On polarized surfaces of low degree whose adjont bundles are not spanned
Gian Mario Besana, Sandra Di Rocco
Smooth complex surfaces polarized with an ample and globally generated line bundle of degree three and four, such that the adjoint bundle is not globally generated, are considered.…
On the k-normality of some projective manifolds
Alberto Alzati, Gian Mario Besana
A long standing conjecture, known to us as the Eisenbud Goto conjecture, states that an n-dimensional variety embedded with degree in the - dimensional projective space is $…
On The Projective Normality of Smooth Surfaces of degree nine
Gian Mario Besana, Sandra Di Rocco
We investigate the projective normality of smooth, linearly normal surfaces of degree 9. All non projectively normal surfaces which are not scrolls over a curve are classified. Res…
