Brauer classes in moduli problems and arithmetic: Lecture 1

Speaker: Nicholas Addington, Sara Frei

Date: Mon, Aug 2, 2021

Location: Online

Conference: PRIMA 2021 Summer School: Rational curves and moduli spaces in arithmetic geometry

Subject: Mathematics

Class: Scientific

Abstract:

We cover Brauer classes, how they arise as obstructions on moduli spaces of sheaves, and how they can be used to obstruct rational points, highlighting recent links between the two.
