A highly focused workshop on recent developments in Brauer groups and derived categories, suitable for people working in the field, organized around a mini-course by each speaker.


James Hotchkiss (Columbia)

Alex Perry (Michigan)

Laura Pertusi (Milano)


We will start at 3pm on Friday and conclude by 2pm on Sunday.


Benjamin Antieau, Andrei Caldararu, Max Lieblich, Akhil Mathew, Martin Olsson


Register here no later than 2 October 2023; for funding, register no later than 14 September 2023.


Some funding is available for graduate students, early-career researchers, and others. To apply for it, your registration must be received by 14 September 2023, with decisions made by 21 September 2023. For funding, graduate students must have a letter of recommendation submitted on their behalf to me, at antieau@northwestern.edu, no later than the deadline above.


Participants, even those we fund, are asked to book their own lodging and be reimbursed. We will book lodging for speakers. Suitable hotels include the Hyatt House Evanston and the Hilton Orrington Evanston.

Added 31 August: the weekend of the workshop is Family Weekend at Northwestern. As a consequence, hotel rooms are scarce and expensive. If you have not already booked, you should do so soon. If that fails, you might look on airbnb or book a hotel in downtown Chicago, near Oglivie Station. From there, you can take the Metra UP-N Line easily to Evanston. The train runs every 30 minuts at rush hour and every 60 minutes at off-peak times, but takes only 23 minutes to get to the Evanston Davis stop, from which campus is a 15 minute walk.


Northwestern is accessible via Amtrak through Chicago Union Station and via plane through Chicago O’Hare or Midway airports. One can take a cab from any of these stations or take public transportation on the Red or Purple ‘L’ Lines or on the UP-N Line of the Metra.


Annenberg Hall G21 on Friday afternoon. Swift Hall 107 on Saturday and Sunday.


Parking is available at either the South or North Campus Parking Garage for $9/day. The South Garage is a 5-10 minute walk from the location of the conference, the North Garage is a 15-20 minute walk. For more details, see here.


This conference is funded by the NSF grant DMS-2152235, FRG: higher categorical structures in algebraic geometry. The image above was created at deepai.org with the prompt “Brauer group”.
