Query: Exponential suppression of radiatively induced mass in the truncated
  overlap   A certain truncation of the overlap (domain wall fermions) contains $k$
flavors of Wilson-Dirac fermions. We show that for sufficiently weak lattice
gauge fields the effective mass of the lightest Dirac particle is exponentially
suppressed in $k$. This suppression is seen to disappear when lattice topology
is non-trivial. We check explicitly that the suppression holds to one loop in
perturbation theory. We also provide a new expression for the free fermion
propagator with an arbitrary additional mass term.
