Gauged supergravities in 5 and 6 dimensions from generalised Scherk-Schwarz reductions

TL;DR

This paper demonstrates how Scherk-Schwarz reductions of M-theory within a duality-invariant framework produce gauged supergravities in 5 and 6 dimensions, aligning local symmetries with known structures.

Contribution

It shows that the duality-invariant formalism reproduces known gauged supergravity structures from non-geometric compactifications.

Findings

Reduction reproduces known gauged supergravity structures.

Local symmetries match embedding tensor gauge transformations.

Framework applies to non-geometric compactifications.

Abstract

It is shown that the Scherk-Schwarz reduction of M-theory in the Berman-Perry duality invariant formalism to 6 and 5 dimensions reproduces the known structures of gauged supergravities that are normally associated to non-geometric compactifications. The local symmetries defined by the generalised Lie derivative reduce to gauge transformations that exactly match those given by the embedding tensor of gauged supergravity.
