We study the lattice N=1 Wess-Zumino model in two dimensions and we constructa sequence $\rho^{(L)}$ of exact lower bounds on its ground state energydensity $\rho$, converging to $\rho$ in the limit $L\to\infty$. The bounds$\rho^{(L)}$ can be computed numerically on a finite lattice with $L$ sites andcan be exploited to discuss dynamical symmetry breaking. The transition pointis determined and compared with recent results based on large-scale GreenFunction Monte Carlo simulations with good agreement.Comment: 32 pages, 12 figure
