Description
This talk is about a canonical quantization of Lie bialgebra structures on the loop algebra with coefficients in the semi-direct product of a simple complex Lie algebra and its dual. The quantization gives rise to twists of the natural analog of the Yangian for this algebra. The Yangian admits a meromorphic R-matrix, which relates its coproduct with a meromorphic coproduct. The construction of the Yangian is motivated by the fact that its representations can be interpreted as perturbative line operators in a 4d holomorphic topological gauge theory. This talk is based on the following joint work with Wenjun Niu: arXiv:2405.19906.
