Top Down Approach to Generalized Symmetries in Quantum Field Theory and Quantum Gravity

Explore a top-down approach to generalized symmetries in quantum field theory and quantum gravity in this hour-long conference talk. Delve into the deep topological structures connected with global symmetries in quantum field theory, known as generalized global symmetries or global categorical symmetries. Learn how string theory's extra dimensions can be used to track these generalized symmetries in QFTs and their fate in quantum gravity. Discover the importance of symmetries in physics and mathematics, and understand why global symmetries are expected to be absent in quantum gravity. Gain insights into new physical objects predicted through this systematic approach, as presented by Jonathan Jacob Heckman at #ICBS2024.
