Persistence of the Brauer-Manin obstruction on cubic surfaces

Carlos Rivera, Bianca Viray

Let $X$ be a cubic surface over a global field $k$ . We prove that a Brauer-Manin obstruction to the existence of $k$ -points on $X$ will persist over every extension $L / k$ with degr…

Quadratic points on intersections of two quadrics

Brendan Creutz, Bianca Viray

We prove that a smooth complete intersection of two quadrics of dimension at least $2$ over a number field has index dividing $2$ , i.e., that it possesses a rational $0$ -cycle of d…
