Abstract
We consider a supersymmetric string model in zero dimensions. The model is defined by a random matrix model containing fermionic degrees of freedom. This model is closely related to bosonic two-dimensional gravity coupled with c=−2 conformal matter (−2-dimensional string theory). When Nicolai's mapping is degenerate, there exists a critical point and the continuum limit can be defined to all orders in the genus expansion. We consider the string susceptibility and compare it with those of the known two-dimensional gravity theories.
