Solvable Descent and the Grunwald Problem for Solvable Groups

Julian L. Demeio

We prove a suitable fibration theorem over quasi-trivial tori that, through an approach developed by Harpaz and Wittenberg, implies so-called solvable descent. In particular, this…

Galois Realisations of $PSL_{2} (F_{p^{2}})$ via non-unirational Hilbert Irreducibility

Julian Demeio, DamiÃ¡n Gvirtz-Chen

We establish non-unirational versions of Hilbert Irreducibility for all Hilbert modular surfaces which are of K3 type. As an application we prove new instances of the regular Inver…

The Brauer group of tori

Julian Demeio

We show that the map $Br T \to (Br T_{k ˉ})^{I^_{k}}$ is surjective for a torus $T$ defined over a field $k$ of characteristic $0$ when $k$ is a loca…
