PSEUDODUALITY IN SUPERSYMMETRIC SIGMA MODELS

Abstract

We study the pseudoduality transformation in supersymmetric sigma models. We generalize the classical construction of pseudoduality transformation to supersymmetric case. We perform this both by component expansion method on manifold [Formula: see text] and by orthonormal coframe method on manifold [Formula: see text]. The component expansion method yields the result that pseudoduality tranformation is not invertible at all points and occurs from all points on one manifold to only one point where Riemann normal coordinates are valid on the second manifold. Torsion of the sigma model on [Formula: see text] must vanish while it is nonvanishing on [Formula: see text], and curvatures of the manifolds must be constant and the same. In the case of super-WZW sigma models, pseudoduality equations result in three different pseudoduality conditions; identity, chiral and antichiral pseudoduality.
