TITLEDiscrete Fluxes, Higher-Form Symmetries and Ward Identities

ABSTRACT We clarify the recently proposed notion of higher-form symmetries using the example of discrete electric and magnetic fluxes. Applying Noether’s second theorem, we show the existence of higher-form symmetries whenever there are constant gauge transformations. Finally, we explain the higher Ward identity which is a consequence at the quantum level.
