The Brauer-Manin obstruction plays a crucial role in the study of rational points on varieties over global fields.

WebFeb 2, 2024 · Unlike the classical Brauer group of a field, the Brauer-Grothendieck group of a singular scheme need not be torsion. We show that there exist integral normal projective surfaces over a large field of positive characteristic with non-torsion Brauer group. In contrast, we demonstrate that such examples cannot exist over the algebraic closure of a … notoriety challenges

The classical theory of central simple algebras and Brauer groups over fields was generalized to schemes by Grothendieck [10]. One important question of Grothendieck was whether the injective Brauer map δ: Br (X) → Br δ: Br (X) → Br how to sharpen images in adobe
