This is the course homepage of a lecture series I am giving at UC Berkeley during the Fall 2026 semester
Lecture schedule
Part 1: the XXX spin chain and the definition of the Yangian for sl_n
Tuesday 1st September: XXX spin chain lecture 1
Thursday 3rd September: QYBE, integrable heirarchy
Tuesday 8th September: The Yangian, and some of its fundamental properties
After part 1, the course will concentrate on geometric representation theory/cohomological Hall algebras/BPS cohomology. There are lots of ways to structure that, please let me know if you have a preference here
Notes will start to appear on this page as the lecture course takes shape.
