我们考虑了用一个u -对偶群值Scherk-Schwarz扭转对m理论的对偶不变方法的约简。结果是产生通常与非几何紧化相关的测量超重力的势。局域对称简化为量规变换，量规与嵌入张量方法的量规完全匹配。重要的是，这种方法现在包含了场对扩展空间的额外坐标的非平凡依赖。
We consider the reduction of the duality invariant approach to M-theory by a U-duality group valued Scherk-Schwarz twist. The result is to produce potentials for gauged supergravities that are normally associated with non-geometric compactifications. The local symmetry reduces to gauge transformations with the gaugings exactly matching those of the embedding tensor approach to gauged supergravity. Importantly, this approach now includes a nontrivial dependence of the fields on the extra coordinates of the extended space.
