# Abstract Andrew Kresch

**Andrew Kresch** will speak on

** Brauer groups and formal gerbes**

In his foundational works on Brauer groups of schemes, Grothendieck raised

a question about the behavior of the Brauer group in the setting of a

scheme, proper over a complete DVR. We address this question using

gerbes on the associated formal scheme. This is work in progress,

joint with Siddharth Mathur.
