文摘

We prove that abelian Yang–Baxter deformations of superstring coset σ models are equivalent to sequences of commuting TsT transformations, meaning T dualities and coordinate shifts. Our results extend also to fermionic deformations and fermionic T duality, and naturally lead to a TsT   subgroup of the superduality group OSp(db,db|2df)OSp(db,db|2df). In cases like AdS5×S5AdS5×S5, fermionic deformations necessarily lead to complex models. As an illustration of inequivalent deformations, we give all six abelian deformations of AdS3AdS3. We comment on the possible dual field theory interpretation of these (super-)TsT models.
