Abstract
The fermion propagator and the vacuum polarization tensor of the Schwinger model are studied on the random block lattice, in the free field limit and weak coupling perturbation theory, respectively. The ensemble averaged fermion propagator and the vacuum polarization tensor agree with their respective values in the continuum theory for distances greater than three average lattice spacings. In momentum space, the ensemble averaged fermion propagator also agrees with the continuum propagator. These results support the possibility of having a chiral fermion interacting with the dynamical gauge field, on the random block lattice, with the correct continuum limit. © 1989.
