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…

Severi varieties on blow--ups of the symmetric square of an elliptic curve
Ciro Ciliberto, Thomas Dedieu, Concettina Galati +1
We prove that certain Severi varieties of nodal curves of positive genus on general blow-ups of the twofold symmetric product of a general elliptic curve are non-empty and smooth o…
