Categorical Wall Crossing in 2d QFT and Beyond
Davis Spring School, May 10-15 2020
We are pleased to announce a six-day school on categorical wall crossing, led by
Principal mentor: Greg Moore (Rutgers)
Supporting mentors: Will Donovan (Tsinghua), Andrew Neitzke (Yale), Fei Yan (Rutgers)
Organizing committee: Roger Casals, Tudor Dimofte, and Harold Williams (UC Davis/QMAP), and Philsang Yoo (Yale).
The school will feature a series of lectures on the physical work Algebra of the Infrared by Gaiotto-Moore-Witten, focusing on categorical structures in massive 2d N=(2,2) quantum field theory, and the categorification of the Cecotti-Vafa wall crossing formula. This will be complemented by lectures and discussions on the mathematical framework of Kapranov-Kontsevich-Soibelman, based on perverse sheaves and schobers; and potential connections and generalizations to wall crossing in 4d N=2 theories.
Lectures will be given both by mentors and by selected participants.
A principal aim of the school is to connect physical and mathematical perspectives on categorical wall crossing.
In addition to lectures, there will be guided discussions and problem sessions.
The target audience is graduate students (both from math and physics) and postdocs. We hope to be able to provide shared local accommodation for graduate students.
If you would like to attend, please complete the Application Form on or before February 29, 2020.
Graduate students: please ask your advisor to email a brief recommendation to firstname.lastname@example.org, by the same deadline.
Senior (faculty level) researchers: if you would like to attend, please either complete the application form or contact the organizers directly.
The application includes an optional request to provide diversity information. This information will be used to prioritize the participation and funding of women and members of other underrepresented groups in mathematics and physics.
Lecture notes and videos will be made available on this website.
