Explore generalized symmetries and their gauging in two-dimensional conformal field theories (2d CFTs) in this comprehensive lecture. Begin with a brief review of 2d CFT fundamentals before delving into the concept of generalized, non-invertible symmetries, presented through explicit CFT observables. Discover how these symmetries are formalized using fusion categories and learn the process of implementing gauging for such symmetries. Examine the physical implications of these mathematical structures and their relevance in the field. Delivered by Yifan Wang from New York University, this 1 hour and 34 minute talk offers an in-depth exploration of advanced topics in theoretical physics and mathematics.
