The wild Brauer-Manin obstruction
Abstract
A way to study rational points on a variety is by looking at their image in the p-adic points. Some natural questions that arise are the following: is there any obstruction to weak approximation on the variety? Which primes might be involved in it? I will explain how primes of good reduction can play a role in the Brauer-Manin obstruction to weak approximation, with particular emphasis on the case of K3 surfaces.

Hello all, we are the Mirzakhani Society, a group for all the women and non-binary mathematicians at Oxford. We run lots and lots of relaxed events from pizza nights to career conferences. Our main aim is to create a warm and welcoming environment for women* to come together and chat about life, maths and anything in-between.
