Effectivity of Brauer-Manin obstructions on surfaces

Andrew Kresch, Yuri Tschinkel

Research output: Contribution to journalArticlepeer-review


We study Brauer-Manin obstructions to the Hasse principle and to weak approximation on algebraic surfaces over number fields. A technique for constructing Azumaya algebra representatives of Brauer group elements is given, and this is applied to the computation of obstructions.
