We prove that a smooth proper universally CH_0-trivial variety X over a field k has universally trivial Brauer group. This fills a gap in the literature concerning the p-torsion of…

Unramified Brauer groups of conic bundle threefolds in characteristic two
Asher Auel, Alessandro Bigazzi, Christian Böhning +1
We establish a formula for computing the unramified Brauer group of tame conic bundle threefolds in characteristic 2. The formula depends on the arrangement and residue double cove…
