References and topics

The goal of the seminar is to understand specific examples of integrable systems with a view towards their relationship with supersymmetric gauge theories and enumerative geometry. More specifically:

1. Spin chains, lattice models, Bethe ansatz. There are many resources for this. A few good ones are https://arxiv.org/abs/1010.5031, and the introduction to Jimbo, Miwa Algebraic Analysis of Solvable Lattice Models.
2. Relationship with supersymmetric vacua/topological theories/enumerative geometry. Key papers are Nekrasov-Shatashvilli https://arxiv.org/abs/0901.4748, https://arxiv.org/abs/0901.4744 from a physical perspective and the mathematical papers by Aganagic-Okounkov https://arxiv.org/abs/1704.08746 and Pushkar, Smirnov, Zeitlin https://arxiv.org/abs/1612.08723
3. At some point it would be good to see talks on the KdV, KP, and Toda lattice hierarchies. E.g. from Date, Jimbo, Miwa Solitons: Differential Equations, Symmetries and Infinite Dimensional Algebras.
4. Other approaches including the sequence Costello-Witten-Yamazaki https://arxiv.org/abs/1709.09993 https://arxiv.org/abs/1802.01579 and Costello-Yamazaki https://arxiv.org/abs/1908.02289.
