Samenvatting
We study the distribution of the Brauer group and the frequency of the Brauer-Manin obstruction to the Hasse principle and weak approximation in a family of smooth del Pezzo surfaces of degree four over the rationals. We also study the geometry and arithmetic of a genus one fibration with two reducible fibres for which a Brauer element is vertical.
