Nonlinear Schrödinger and Korteweg–de Vries from 4d Chern–Simons theory
Geometry and Mathematical Physics Seminar Speaker: Roland Bittleston (Harvard University) Title: Nonlinear Schrödinger and Korteweg–de Vries from 4d Chern–Simons theory Abstract: Over the past decade, four-dimensional Chern–Simons theory has emerged as a powerful organising principle for two-dimensional integrability. In this talk, I will directly recover the Lax formulations and variational principles of two archetypal integrable […]
