Description
Comments on topological field theory and anomalies
Abstract: In the last years the paradigm for understanding the symmetries of quantum field theories has shifted towards the concept of the so called SymmetryTFT, a topological field theory encoding the data of all possible realizations of global and higher group structures. In this brief talk we will review some aspects of topological field theory and how standard techniques allow to reinterpret anomalies in term of topological invariants. As an example, we will discuss the case of 5d SCFT constructed via geometric engineering, commenting in particular the relation between wrapped branes, topological operators and generalized membranes link.
