SUMMARY:Nonlinear Schrödinger and Korteweg–de Vries from 4d Chern–Simons theory
DESCRIPTION:Geometry and Mathematical Physics Seminar \nSpeaker: Roland Bittleston (Harvard University) \nTitle: Nonlinear Schrödinger and Korteweg–de Vries from 4d Chern–Simons theory \nAbstract: 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 systems within this framework: the nonlinear Schrödinger and Korteweg–de Vries equations. The key ingredients are singular boundary conditions supplemented by compensating source terms\, in a construction reminiscent of open boundary conditions in three-dimensional Chern–Simons theory.

SUMMARY:The work of Jacob Tsimerman (ICM series)
DESCRIPTION:CMSA Q&A Seminar \nSpeaker: Aaron Landesman (Harvard CMSA) \nTitle: The work of Jacob Tsimerman (ICM series) \nAbstract: I will discuss some basics of the Fields Medal work of Jacob Tsimerman. Some of his key contributions come toward the André-Oort conjecture\, algebraicity of period maps\, and arithmetic statistics.
