Summer School in Geometric Representation Theory

Coulomb Branches and Knot Homology

Lecturer: Ben Webster (Perimeter/Waterloo)

June 19-23, 2023
MIT, Cambridge, MA


This will be an intensive, 5-day summer school geared toward graduate students in geometric representation theory. Topics include symplectic resolutions of singularities, particularly the recent construction of Coulomb branches due to Braverman, Finkelberg and Nakajima, categories of coherent sheaves on these spaces, derived equivalences between these categories, and relations to quantum field theory. Prerequisites are the equivalent of one year graduate courses in algebraic geometry, Lie theory and algebraic topology.


The talks will start at 9:15 every day between June 19 and June 23, and last well into the afternoon every day except Friday. See the link below for the precise day-by-day schedule, as well as mathematical details. All talks will be held in room 2-190 in the MIT Department of Mathematics. We will be having coffee and pastries every morning at 8:45 in room 2-290.

Summer School Syllabus and Schedule


Lodging is very expensive in Cambridge in June, so if you have family or friends you can stay with, that would be easiest. Otherwise, please ask your advisor/department if they can cover the costs of lodging and travel (and we can help you find a room even if paying with your own funds, just let us know on the registration form).

For graduate students only: we have some funding available for lodging and travel, and please indicate whether you need any on your registration form (Deadline: February 28, 2023). In this case, please ask your advisor to email a short letter of recommendation to Rosalee Zammuto ( If we'll be able to support you, we can reimburse plane/train/bus travel to the Boston area (so not local taxis) capped at the following amounts depending on your geographic location.

Northeast: $300
Midwest and Southeast: $500
West and Southwest: $800
