摘要：The recently proposed construction of chiral fermions on lattices with boundaries is tested in
an interacting theory up to first order of perturbation theory. We confirm that, in the bulk of
the lattice, the chiral Ward identities take their continuum value up to cutoff effects without any
tuning. Universal quantities are defined that have an expansion in the renormalised couplings
with coefficients that are functions of the physical size and the periodicity in the spatial direction.
These coefficient functions have to be identical for different discretisations. We find agreement
with the standard Wilson fermions. The computation is done in the asymptotically free Gross-
Neveu model with continuous chiral symmetry.
