Description
Brane constructions of generalized symmetry operators are well understood in many cases. For example, given a QFT engineered by a local geometry in string theory such operators arise via brane wrappings on asymptotic cycles. When the local geometry is embedded into a global one the notion of asymptotic cycle is lost, gravity is turned on and symmetries are either gauged or broken following the no global symmetries folk theorem. We give a simple geometric characterization of these gauging and breaking phenomena.
