A remark on isolated complex hypersurface singularities
Fabrizio Catanese, Ciro Ciliberto, Concettina Galati
This is now an expository note about the following classical problem. Let be the germ of a hypersurface in with an ordinary singularity of multip…
On nodal deformations of singular surfaces in
Ciro Ciliberto, Concettina Galati
In this paper we study nodal deformations of singular surfaces . In particular we consider the case in which has an isolated singularity of multiplicity $…
The Caporaso-Harris-Ran degeneration principle: proof and applications
Francesco Bastianelli, Ciro Ciliberto, Thomas Dedieu +3
Severi varieties are the parameter spaces for curves with prescribed homology class and genus on a smooth surface. We describe their limits along degenerations of surfaces, with a…
Limits of nodal surfaces and applications
Ciro Ciliberto, Concettina Galati
Let be a flat family of projective complex 3-folds over a disc with smooth total space and smooth general fibre an…
Rational curves and Seshadri constants on Enriques surfaces
Concettina Galati, Andreas Leopold Knutsen
We prove that classes of rational curves on very general Enriques surfaces are always -divisible. As a consequence, we prove that the Seshadri constant of any big and nef line b…
Nonemptiness of Severi varieties on Enriques surfaces
Ciro Ciliberto, Thomas Dedieu, Concettina Galati +1
Let be a general polarized Enriques surface, with not numerically 2-divisible. We prove the existence of regular components of all Severi varieties of irreducible -n…
