Student Arithmetic Seminar

Central Simple Algebras and the Brauer Group
Wednesday, March 20, 2019
4:00-5:00 PM
3088 East Hall Map
Central simple algebras (CSA) play an important role in class field theory, formalized in terms of cohomology theory.

The plan for the talk is to introduce CSA and the Brauer group. There are several ways of interpreting the Brauer group. We will mention the Galois descent method, the second cohomology interpretation and the geometric view through Severi-Brauer variety.

The basic example is quaternion algebra. We will examine how this concrete example fits into the general picture.

Hope to see you there! Speaker(s): Hang Yin (University of Michigan)
