Query: Topological Effects in Matrix Models representing Lattice Gauge Theories
  at Large N   Quenched reduction is revisited from the modern viewpoint of
field-orbifolding. Fermions are included and it is shown how the old problem of
preserving anomalies and field topology after reduction is solved with the help
of the overlap construction.
