Subject: Higher symmetry ’t Hooft anomalies and domain walls

We first review the zero-form/one-form ’t Hooft anomaly matching conditions, using the example of the charge-Q massless Schwinger model. This is the simplest quantum field theory with such anomalies and their manifestation can be seen from different points of view. We will then argue that the Q=2 case and its various generalizations are relevant for the physics of domain walls in four-dimensional super-Yang-Mills theory and adjoint QCD and will show how various aspects of bulk/domain wall interactions found earlier via string theory can be seen in a purely field theoretic setting.
