Quartic del Pezzo surfaces over $F_{p} (t)$ without quadratic points

Giorgio Navone, Katerina Santicola, Harry C. Shaw +1

We construct an infinite family of quartic del Pezzo surfaces over $F_{p} (t)$ with no quadratic points, for all primes $p \neq = 2$ . This answers a question of Colliot--Thélène…

Description of the strong approximation locus using Brauer-Manin obstruction for homogeneous spaces with commutative stabilizers

Victor de Vries, Haowen Zhang

For a homogeneous space $X$ over a number field $k$ , the Brauer-Manin obstruction has been used to study strong approximation for $X$ away from a finite set $S$ of places, and know…
