在考虑背景通量和高阶导数项的情况下，通过11维超引力获得的bstractM理论在8维紧致空间中存在全局一致的翘曲解.内部背景是共形Kähler与消失的第一陈类。我们扰动这些解决方案，包括有限数量的Kähler变形的度量和矢量变形的M-理论的三种形式。特别强调的是场的依赖性的翘曲因子和更高的衍生条款。我们表明，三维的二阶导数有效的行动采取了一个令人惊讶的简单的形式，在一个单一的高曲率积木，由于许多非平凡的取消。无论是反量还是有效作用量都承认内部度规的模依赖标度对称性。此外，我们发现，所需的偏离里奇平坦性和调和性的零模本征形不改变有效的理论。
A bstractM-theory accessed via eleven-dimensional supergravity admits globally consistent warped solutions with eight-dimensional compact spaces if background fluxes and higher derivative terms are considered. The internal background is conformally Kähler with vanishing first Chern class. We perturb these solutions including a finite number of Kähler deformations of the metric and vector deformations of the M-theory three-form. Special emphasis is given to the field-dependence of the warp-factor and the higher-derivative terms. We show that the three-dimensional two-derivative effective action takes a surprisingly simple form in terms of a single higher-curvature building block due to numerous non-trivial cancellations. Both the ansatz and the effective action admit a moduli dependent scaling symmetry of the internal metric. Furthermore, we find that the required departure from Ricci-flatness and harmonicity of the zero-mode eigenforms does not alter the effective theory.
