Consistent N=4 , D=4 truncation of type IIB supergravity on S1×S5

Fetching techniques from generalized geometry and exceptional field theory, we develop a new method to identify consistent subsectors of four-dimensional gauged maximal supergravities that possess a (locally) geometric embedding in type IIB or 11D supergravity. We show that a subsector that is invariant under a structure group GS⊂E7(7) can define a consistent truncation, even when GS is not part of the symmetry of the gauged maximal supergravity. As an illustration of the method, type IIB supergravity on S1×S5 is shown to admit a consistent truncation to pure N=4, D=4 gauged supergravity. Explicit uplift formulae are presented which provide a type IIB alternative to the M-theory embedding constructed by Cvetic, Lu, and Pope 25 years ago.
