Gauging Non-Invertible Symmetries in 2+1D TQFTs

Explore the mathematical framework of gauging non-invertible symmetries in 2+1 dimensional topological quantum field theories in this advanced research seminar. Delve into the theoretical foundations and applications of non-invertible symmetries within the context of TQFTs, examining how these symmetries can be gauged and their implications for quantum field theory. Learn about the mathematical structures underlying these symmetries and their role in understanding topological phases of matter. Discover the connections between non-invertible symmetries and boundary conditions, defects, and impurities in quantum field systems. Gain insights into cutting-edge research in mathematical physics and quantum field theory through detailed mathematical exposition and theoretical analysis presented by a researcher from Queen Mary University of London as part of the "Quantum field theory with boundaries, impurities, and defects" program at the Isaac Newton Institute.
