Abstract:

In this talk I will explain the notion of a Tate vector space and how to associate to it a determinant theory. Using this we will get the universal central extension of the group of automorphisms of a Tate space. This universal central extension will also give central extensions of loop groups. I will then explain the higher categorical versions of this constructions: 2-Tate spaces and 2-central extensions. This is joint work with Sergey Arkhipov.
