Physics Group Meeting

I will discuss an approach to integrable models from a four-dimensional Chern-Simons-type gauge theory. For introduction please have a look at E. Witten arXiv:1611.00592 or K. Costello arXiv:1308.0370. It might be interesting to look into some Feynman diagram computations in my paper arXiv:1709.09993 with Edward and Kevin (e.g. section 4 and section 5.2). If I have time I can come to more recent developments.
