The Department of Mathematics and Statistics invites students, faculty and staff to attend a talk given by Dr. Basil Nanayakkara on Thursday, February 1st, 2024 from 1:00 PM to 2:00 PM. The talk is entitled The Brauer group.

For location room number, please email Neil Marshall (nmarshall@brocku.ca).

Abstract:

Let k be a field. The set of all isomorphism classes of finite dimensional central division algebras over k can be endowed with a group structure using the tensor product of k algebras. We will discuss this group, called the Brauer group Br(k) of k and its many ramifications/properties.
