The degree of the bicanonical map of a surface with
Margarida Mendes Lopes, Rita Pardini
In this note it is shown that, given a smooth minimal complex surface of general type S with p_g(S)=0, K^2_S=3, for which the bicanonical map is a morphism, then the degree of the…

Birational characterization of products of curves of genus 2
Christopher D. Hacon, Rita Pardini
Let X be a variety of maximal Albanese dimension. In this paper we prove that if χ(ω_X)=1 then the q(X)<=2dim X and if q(X)=2dim X, then X is birational to a product of curves of g…
