| Abstract: | We demonstrate that vacuum solutions in the Neveu-Schwarz field theory of a fermionic string incorporating the GSO(−) sector
are naturally related to the zero-curvature representation in a graded space of special form. We use the same representation
to describe the equivalence of the cubic and nonpolynomial theories with the GSO(−) sector also taken into account.
