SUMMARY:Seminar: 'Symmetry TFTs for Continuous Spacetime Symmetries'
DESCRIPTION:Title: Symmetry TFTs for Continuous Spacetime Symmetries \nSpeaker: Iñaki Garcia Etxebarria (Durham U.) \nVenue & Time: Red Room / 3:00 PM \nAbstract: I will discuss our recent proposal for the Symmetry Topological Field Theory (SymTFT) for global\, continuous spacetime symmetries ( https://arxiv.org/abs/2509.07965 ). For a d-dimensional theory\, it is given by a (d + 1)-dimensional BF-theory for the spacetime symmetry group\, and whenever d is even\, it includes also Chern-Simons couplings\, that encode conformal and gravitational anomalies. This proposal is supported by the similarity to two- dimensional Jackiw-Teitelboim gravity in the d = 1 case and the topological limit of four-dimensional gravity in the d = 3 case. I will discuss how topological defects constructed from this SymTFT act by applying the associated spacetime symmetry transformation. Finally\, I will discuss the relation to gravity and holography.
