Saito's theorem revisited and application to free pencils of hypersurfaces
Roberta Di Gennaro, Rosa Maria Miró-Roig
A hypersurface is said to be free if its associated sheaf of vector fields tangent to is a free -module. So far few exa…
Castelnuovo-Mumford Regularity and Splitting Criteria for Logarithmic Bundles over Rational Normal Scroll Surfaces
Roberta Di Gennaro, Francesco Malaspina
We introduce and study a notion of Castelnuovo-Mumford regularity suitable for rational normal scroll surfaces. In this setting we prove analogs of some classical properties. We pr…
When the positivity of the h-vector implies the Cohen-Macaulay property
Francesca Cioffi, Roberta Di Gennaro
We study relations between the Cohen-Macaulay property and the positivity of -vectors, showing that these two conditions are equivalent for those locally Cohen-Macaulay equidime…
The equations of space curves on a quadric
Roberta Di Gennaro, Uwe Nagel
The homogenous ideals of curves in a double plane have been studied by Chiarli, Greco, Nagel. Completing this work we describe the equations of any curve that is contained in some…
