Non-Invertible Symmetries, Generalized Gauging and Factorization

Explore a theoretical physics lecture from Oxford University's Christian Copetti examining a toy model for low dimensional holography where the dual theory operates as an ensemble over 2d RCFTs. Delve into the analysis of factorization challenges on multi-boundary geometries and bulk global symmetry, discovering how these issues can be resolved through modifying the path integral prescription with generalized gauging operations. Learn how these operations can alternatively be interpreted as topological EOW brane insertions, providing key insights into non-invertible symmetries and their relationships to generalized gauging in theoretical physics.
