Flat deformations of type IIB S-folds
Abstract Type IIB S-folds of the form AdS4 × S1 × S5 have been shown to contain axion-like deformations parameterising flat directions in the 4D scalar potential and corresponding to marginal deformations of the dual S-fold CFT’s. In this note we present a group-theoretical characterisation of such...
