Duality in N=2 super-Liouville theory

In this paper we consider a strong-weak coupling duality of the N=2 super-Liouville field theory (SLFT). Without the self-duality found in other Liouville theories, the N=2 SLFT, we claim, is associated with a "dual" action by a transformation b→1/b where b is the coupling constant. To justify our conjecture, we compute the reflection amplitudes (or two-point functions) of the Neveu-Schwarz and Ramond operators of the N=2 SLFT based on the conjectured dual action and show that the results are consistent with known results.
