N2 - We present a detailed study of various aspects of Spinor–Vector duality in Heterotic string compactifications and expose its origin in terms of the internal conformal field theory. In particular, we illustrate the main features of the duality map by using simple toroidal orbifolds preserving N4=1 and N4=2 spacetime supersymmetries in four dimensions. We explain how the duality map arises in this context by turning on special values of the Wilson lines around the compact cycles of the manifold. We argue that in models with N4=2 spacetime supersymmetry, the interpolation between the Spinor–Vector dual vacua can be continuously realized. We trace the origin of the Spinor–Vector duality map to the presence of underlying N=(2,2) and N=(4,4) SCFTs, and explicitly show that the induced spectral flow in the twisted sectors is responsible for the observed duality. The isomorphism between current algebra representations gives rise to a number of chiral character identities, reminiscent of the recently-discovered MSDS symmetry
