Title: Non-invertible symmetries in S_N orbifold CFTs and holography
Abstract: This talk is based on two recent papers (arxiv:2405.15693 and 2406.10967) by Y. Li, D. Rathore, K. Roumpedakis and M. Gutperle. We construct non-invertible defects in S_N symmetric orbifolds and discuss the spectrum of defect operators, Ward-identities, entanglement entropy in the presence of defects as well as a proposal for a world sheet dual of the topological defects in the AdS/CFT dual of the symmetric orbifold.
