On NÃ©ron-Severi lattices of Jacobian elliptic K3 surfaces

Adrian Clingher, Andreas Malmendier

We classify all Jacobian elliptic fibrations on K3 surfaces with finite automorphism group. We also classify all Jacobian elliptic fibrations with finite Mordell-Weil group on K3 s…

On projective K3 surfaces $X$ with $Aut (X) = (Z /2 Z)^{2}$

Adrian Clingher, Andreas Malmendier, Xavier Roulleau

We prove that every K3 surface with automorphism group $(Z /2 Z)^{2}$ admits an explicit birational model as a double sextic surface. This model is canonical for Pica…
