Odd order Brauer-Manin obstruction on diagonal quartic surfaces
Ieronymou, Evis; Skorobogatov, A. N. (2015)We determine the odd order torsion subgroup of the Brauer group of diagonal quartic surfaces over the field of rational numbers. We show that a non-constant Brauer element of odd order always obstructs weak approximation ...

On the Brauer group of diagonal quartic surfaces
Ieronymou, Evis; Skorobogatov, A. N.; Zarhin, Y. G. (2011)We obtain an easy sufficient condition for the Brauer group of a diagonal quartic surface D over to be algebraic. We also give an upper bound for the order of the quotient of the Brauer group of D by the image of the Brauer ...
