Generic Torelli theorem for Prym varieties of ramified coverings
Valeria Ornella Marcucci, Gian Pietro Pirola
In this paper we prove that the Prym map, from the space of double coverings of a curve of genus g with r branch points to the moduli space of abelian varieties, is generically inj…
A characterization of the symmetric square of a curve
Margarida Mendes Lopes, Rita Pardini, Gian Pietro Pirola
In this paper a new intrinsic geometric characterization of the symmetric square of a curve and of the ordinary product of two curves is given. More precisely it is shown that the…
On surfaces of general type with q=5
Margarida Mendes Lopes, Rita Pardini, Gian Pietro Pirola
We prove that a complex surface S with irregularity q(S)=5 that has no irrational pencil of genus >1 has geometric genus p_g(S)>7. As a consequence, one is able to classify minimal…
A New Curve Algebraically but not Rationally Uniformized by Radicals
Gian Pietro Pirola, Cecilia Rizzi, Enrico Schlesinger
We give a new example of a curve C algebraically, but not rationally, uniformized by radicals. This means that C has no map onto the projective line P^1 with solvable Galois group,…
