Discretized superstring in three-dimensional superspace
Parthasarathi Majumdar · Physical Review Letters · 1993
The partition function of the discretized superstring in a target superspace of three (Euclidean) bosonic dimensions is shown, for a fixed triangulation of the random world sheet, to be derived from the partition function of a discretized bosonic string with an external field present in the action in the form of a specific constant matrix, using first order forms of the actions. This latter partition function appears more amenable to an exact analytical treatment.
