description The aim of this paper is to make progress in the understanding of the Scherk-Schwarz dimensional reduction in terms of a compactification in the presence of background fluxes/torsion. From the eleven dimensional supergravity point of view, we find that a general E_{6(6)} S-S phase may by obtained by turning on an appropriate background torsion flux, together with suitable fluxes, some of which can be identified with certain components of the four-form field-strength. Our analysis also suggests the interpretation of the torsion flux as the T-dual of the NS three-form flux.

Our analysis also suggests the interpretation of the torsion flux as the T-dual of the NS three-form flux.The aim of this paper is to make progress in the understanding of the Scherk-Schwarz dimensional reduction in terms of a compactification in the presence of background fluxes and torsion. From the eleven dimensional supergravity point of view, we find that a general E6(6) S-S phase may be obtained by turning on an appropriate background torsion, together with suitable fluxes, some of which can be directly identified with certain components of the four-form field-strength. Furthermore, we introduce a novel (four dimensional) approach to the study of dualities between flux/torsion compactifications of Type II/M-theory. This approach defines the action that duality should have on the background quantities, in order for the E7(7) invariance of the field equations and Bianchi identities to be restored also in the presence of fluxes/torsion. This analysis further implies the interpretation of the torsion flux as the T-dual of the NS three-form flux.hep-th/0502083CERN-PH-TH-2005-022FTUV-05-0208IFIC-05-14CERN-PH-TH-2005-022oai:cds.cern.ch:8213092005-02-08
