Geometry/Physics Seminar

Title: Tate spaces and central extensions
Speaker: Kobi Kremnizer
Speaker Info: University of Chicago
Brief Description:
Special Note:

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.
