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…

Numerical Godeaux surfaces with an involution
Alberto Calabri, Ciro Ciliberto, Margarida Mendes Lopes
Minimal algebraic surfaces of general type with the smallest possible invariants have geometric genus zero and K^2=1 and are usually called "numerical Godeaux surfaces". Although t…
