Title: The Branes Behind Generalized Symmetry Operators

 

Abstract: Generalized global symmetries are a common feature of QFTs. Such symmetries are realized via extended topological operators and whenever a QFT admits an embedding into string theory it is natural to expect these to similarly lift to stringy objects. We argue that branes wrapped on asymptotic cycles “at infinity” engineer generalized symmetry operators. This gives a non-Lagrangian method for systematically constructing such topological operators and their fusion ring. We discuss examples.
