Abstract:
Higher form symmetry is a generalized notion of global symmetry, which acts on non-local operators in the physical theory. In the context of quantum field theories, higher form symmetry is an essential piece of data that is not manifest in the Lagrangian. An important question is how to systematically compute the higher form symmetry of a given QFT. In this talk, I will present a brilliant approach via geometric engineering techniques under string theory framework. Many supersymmetric QFTs (including non-Lagrangian ones) are constructed by putting superstring/M-theory on different geometric spaces, whose topological data determines the higher form symmetry of the QFT.
