Axial anomaly in the reduced model: Higher representations


الملخص بالإنكليزية

The topological charge in the $U(N)$ vector-like reduced model can be defined by using the overlap Dirac operator. We obtain its large $N$ limit for a fermion in a general gauge-group representation under a certain restriction of gauge field configurations which is termed $U(1)$ embedding.
