Query: Non-perturbative Aspect of Zero Dimensional Supersring   We discuss the non-perturbative aspect of zero dimensional superstring. The
perturbative expansions of correlation functions diverge as
$\sum_l(3l)!\kappa^{2l}$, where $\kappa$ is a string coupling constant. This
implies there are non-perturbative contributions of order $\e^{C\kappa^{-{2
\over 3}}}$. (Here $C$ is a constant.) This situation contrasts with those of
critical or non-critical bosonic strings, where the perturbative expansions
diverge as $\sum_ll!\kappa^{2l}$ and non-perturbative behaviors go as
$\e^{C\kappa^{-1}}$. It is explained how such nonperturbative effects of order
$\e^{C\kappa^{-{2 \over 3}}}$ appear in zero dimensional superstring theory.
Due to these non-perturbative effects, the supersymmetry in target space breaks
down spontaneously.
