Within the context of a bosonized theory, we evaluate the current-currentcorrelation functions corresponding to a massive Dirac field in 2+1 dimensions,which is constrained to a spatial half-plane. We apply the result to theevaluation of induced vacuum currents in the presence of an external field. Wecomment on the relation with the purely fermionic version of the model, in thelarge-mass limit.
