22. Challenge Talk 2 - Feynman's Last Blackboard: From Bethe Ansatz to Langlands Duality

Edward Frenkel (UC Berkeley)

2023-07-25, 10:15 a.m.

Richard Feynman's last blackboard at Caltech contains a number of tantalizing inscriptions about Bethe Ansatz in quantum integrable models, which fascinated him in the last years of his life. After reviewing some basic examples, I will present a modern perspective on the subject, linking it to dualities in QFT and String Theory, as well as the Langlands duality in mathematics. I will then...
