String theories on a background manifold with torsion are constructed and investigated in the light-cone gauge with holonomy group H ⊆ SU(3). The appropriate non-linear sigma model is constructed on a hermitian manifold. The relationship between the Neveu-Schwarz-Ramond and the Green-Schwarz versions of the theory is discussed. Under the assumption that the β-function vanishes identically we show that the only viable compactification is on a manifold with zero torsion. This result is obtained from effective field considerations as well as directly from string considerations.
