Non-invertible Symmetries of 2d Non-Linear Sigma Models

Explore non-invertible symmetries in two-dimensional non-linear sigma models through this mathematical physics seminar presented by Max Velásquez Cotini Hutt from Imperial College London. Delve into advanced concepts in quantum field theory as part of the "Quantum field theory with boundaries, impurities, and defects" program at the Isaac Newton Institute. Examine the theoretical framework and mathematical structures underlying non-invertible symmetries and their applications to 2d non-linear sigma models, gaining insights into this cutting-edge area of theoretical physics research.
