Topological String on OSP(1|2)/U(1)
Abstract
We propose an equivalence between topological string on OSP(1|2)/U(1) and c ≤ 1 superstring with N=1 world-sheet supersymmetry. We examine this by employing a free field representation of OSP(1|2) WZNW model and find an agreement on the spectrum. We also analyze this proposal at the level of scattering amplitudes by applying a map between correlation functions of OSP(1|2) WZNW model and those of N=1 Liouville theory.
