Saghar Sophie Hosseini - Symmetry TFTs of geometrically engineered field theories

(D+1)-dimensional topological field theories, known as SymTFTs, contain information about choices of generalised global symmetries and anomalies of D-dimensional QFTs. In this talk, I will introduce SymTFTs and explain how the BF theory, classifying higher-form symmetries, may be obtained from the dimensional reduction of a Chern-Simons action for self-dual fields in string theory.
