SUMMARY:Line operators in holomorphic QFT
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Keyou Zeng (CMSA) \nTitle: Line operators in holomorphic QFT \nAbstract: We will discuss the recent work (arxiv:2508.11749)\, which defines the so called dg shifted Yangian. I will discuss their origin from the study of 3d holomorphic topological field theories\, a variant of 3d TQFT. A dg shifted Yangian is supposed to control the fusion of line defect in the corresponding 3d HT theories. I will illustrate these discussions in examples.
