Description
Many non-Lagrangian and strongly coupled quantum field theories (QFTs) can be realized via string constructions. These often serve as progenitor theories for large families of QFTs which in this setting admit constructions via deformation and compactification of the former. As standard, the dynamics of such QFTs are constrained by symmetries, and in this talk we discuss how to map a given string construction onto the symmetry data of the associated QFT. We focus on geometrically engineered QFTs (with dual brane constructions) and characterize their symmetries, and their anomalies, via a system of topological quantum field theories. The methods presented avoid the complicated dynamics of the QFT and we present their application to superconformal QFTs in 5D and 6D.
