| Jun 24, 2020 at 15:48 | comment | added | R.P. | I think yes, and it should follow from the Künneth formula (the involution acting as $-1$ on $H^1$, and so as $(-1)^2 = 1$ on $H^2$). I realize I am not giving enough details to be 100% persuasive, but I am very far from being an expert on this. I think the paper by Skorobogatov and Zarhin on the Brauer group of Kummer surfaces must contain enough details to construct a proof though. | |
