Abstract: We present our study of the N=2 supersymmetric lattice theory in two
dimensions proposed by Cohen, Kaplan, Katz, and Unsal. The stability of the
vacuum and the susy breaking counter term at the quantum level are examined
by an explicit calculation. In this analysis, we make one-loop perturbative
approximation for the nozero momentum modes, while zero modes are treated
nonperturbatively. We find that the counter term appears in the continuum
limit but vanishes in the infite volume. We also show that a special treatment
of the fermionic zero modes is required in order to have a well-defined pathintegral.
