报告摘要：

In this talk, I will give a review of 4d Chern-Simons theory (4d CS). 4d CS was put forward by K. Costello, E. Witten, and M. Yamazaki in 2017. They use the theory to construct 2d integrable models in 1908.02289. There are two kinds of 4d CS called the disorder defect case and the order defect case. Some sigma-models are constructed by the former one and some models with current-current-like interaction are constructed by the latter one. My talk will focus on how the theory works and why models constructed from the theory are integrable.
