On the Brauer-Manin obstruction for cubic surfaces
Andreas-Stephan Elsenhans, Jörg Jahnel
We describe a method to compute the Brauer-Manin obstruction for smooth cubic surfaces over such that $\Br(S)/\Br(\bbQ)$ is of order two or four. This covers the vast majori…

Determinantal quartics and the computation of the Picard group
Andreas-Stephan Elsenhans, Jörg Jahnel
We test the methods for computing the Picard group of a surface in a situation of high rank. The examples chosen are resolutions of quartics in $\bP^3$ having 14 singularities…

The discriminant of a cubic surface
Andreas-Stephan Elsenhans, Jörg Jahnel
We construct explicit examples of cubic surfaces over such that the 27 lines are acted upon by the index two subgroup of the maximal possible Galois group. This is the simpl…
