Wild Brauer classes via prismatic cohomology

Emiliano Ambrosi, Rachel Newton, Margherita Pagano

Let $K$ be a finite extension of $Q_{p}$ and $X$ a smooth proper $K$ -variety with good reduction. Under a mild assumption on the behaviour of Hodge numbers under reduction m…

A survey of local-global methods for Hilbert's Tenth Problem

Sylvy Anscombe, Valentijn Karemaker, Zeynep Kisakürek +3

Hilbert's Tenth Problem (H10) for a ring R asks for an algorithm to decide correctly, for each $f \in Z [X_{1}, \dots, X_{n}]$ , whether the diophantine equation $f(X_{1},...,X_…

The role of primes of good reduction in the Brauer--Manin obstruction

Margherita Pagano

We discuss the role of primes of good reduction in the existence of the Brauer--Manin obstruction to weak approximation for varieties defined over number fields. Following Bright a…
