N2 - We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma-models on AdS backgrounds with Ramond-Ramond fluxes in various dimensions. We show that sigma-models based on supercosets of PSU supergroups, such as AdS 2 × S 2 and AdS 3 × S 3 are self-dual under fermionic T-duality, while supercosets of OSp supergroups such as non-critical AdS 2 and AdS 4 models, and the critical AdS 4 × P 3 background are not. We present a general algebraic argument to when a supercoset is expected to have a fermionic T-duality symmetry, and when it will fail to have one.
