Description
In this talk, I will explain how to construct integrable sigma models with time-dependent couplings from 4d Chern-Simons. I will start by reviewing the basics of integrable sigma models, as well as the appropriate modifications to accommodate time-dependent coupling parameters. The main goal of this talk will be to present some useful frameworks for studying these integrable systems. At the forefront will be 4d Chern-Simons — a holomorphic-topological gauge theory which describes 2d integrable systems. If time permits, I may also touch on applications of twistor theory and 6d holomorphic Chern-Simons in this context.
