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 of the expected dimension. This result, besides its intrinsic value, is an important preliminary step for the proof of nonemptiness of Severi varieties on general Enriques surfaces in [7]. 


Geometry of families of nodal curves on the blown-up projective plane

Severi varieties and branch curves of abelian surfaces of type (1,3)
Let (A,L) be a principally polarized abelian surface of type (1,3). The linear system |L| defines a 6:1 covering of A onto P2, branched along a curve B of degree 18 in P2. The main result of theExpand

We prove that the irreducible components of primitive class Severi varieties of general abelian surfaces are completely determined by the maximal factorization through an isogeny of the maps from theExpand
On the Symmetric Product of a Curve with General Moduli
We study the problem of describing the cone of the effective divisors in the second symmetric product of a curve with general moduli using a degeneration to a rational g-nodal curve.
A Note on Severi Varieties of Nodal Curves on Enriques Surfaces
Let |L| be a linear system on a smooth complex Enriques surface S whose general member is a smooth and irreducible curve of genus p, with L2 > 0, and let V|L|,δ(S) be the Severi variety ofExpand
Counting plane curves of any genus
We obtain a recursive formula answering the following question: How many irreducible, plane curves of degree d and (geometric) genus g pass through 3d-1+g general points in the plane? The formula isExpand
