Brauer Groups of Bielliptic Surfaces and Twisted Derived Equivalences

Vodrup, Magnus Røen (Doctoral thesis, 2021-08-30)

This thesis focuses on two interrelated projects. The first project concerns the study of bielliptic surfaces, their Brauer groups and the pullback maps from their Brauer groups to those of their canonical covers. We prove ...
On the Brauer group of bielliptic surfaces (with an appendix by Jonas Bergström and Sofia Tirabassi)

Ferrari, Eugenia; Tirabassi, Sofia; Vodrup, Magnus Røen; Bergström, Jonas (Journal article; Peer reviewed, 2022)

We provide explicit generators of the torsion of the second cohomology of bielliptic surfaces, and we use this to study the pullback map between the Brauer group of a bielliptic surface and that of its canonical cover.
