Effectivity of Brauer–manin Obstructions on Surfaces
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.

متن کاملThe Brauer–manin Obstructions for Homogeneous Spaces with Connected or Abelian Stabilizer
In this paper we prove that for a homogeneous space of a connected algebraic group with connected stabilizer and for a homogeneous space of a simply connected group with abelian stabilizer, the Brauer–Manin obstructions to the Hasse principle and weak approximation are the only ones. More precisely, let X be an algebraic variety over a number field k. The variety X is called a counter-example t...
متن کاملDescent obstructions and Brauer-Manin obstruction in positive characteristic
We prove that the Brauer-Manin obstruction is the only obstruction to the existence of integral points on affine varieties over global fields of positive characteristic p. More precisely, we show that the only obstructions come from étale covers of exponent p or, alternatively, from flat covers coming from torsors under connected group schemes of exponent p.
