  A nonperturbative formulation of the Wess-Zumino (WZ) model in two and three
dimensions is proposed on the basis of momentum-modes truncation. The
formulation manifestly preserves full supersymmetry as well as the
translational invariance and all global symmetries, while it is shown to be
consistent with the expected locality to all orders of perturbation theory. For
the two-dimensional WZ model, a well-defined Nicolai map in the formulation
provides an interesting algorithm for Monte Carlo simulations.
