标题： How to uplift non-maximal gauged supergravities

摘要： 在本文中，我们提供了一个算法，用于将非最大值$G_g$-规范超引力提升到类型 IIB 或 11D 超引力。 使用例外场理论和广义几何的工具，我们表明内部流形具有$G_g$-作用，并且提升的一致性等价于在商空间$M_{\text{int}}/G_g$上求解一个更简单的偏微分方程。 作为应用，我们对纯半最大四维$\textrm{SO}(4)$-规范超引力的所有可能提升进行了分类，并在任何 D'Hoker-Estes-Gutperle 解周围恢复了一致截断\cite{DHoker:2007hhe}。 显示英文摘要

摘要： In this paper, we provide an algorithm to perform the uplift of non-maximal $G_g$-gauged supergravities to type IIB or 11D supergravities. Using tools of exceptional field theory and generalised geometry, we show that the internal manifold admits a $G_g$-action, and that consistency of the uplift is equivalent to solving a simpler PDE on the quotient $M_{\text{int}}/G_g$. As an application, we classify all possible uplifts of pure half-maximal four-dimensional $\textrm{SO}(4)$-gauged supergravity to type IIB and we recover consistent truncations around any of the D'Hoker-Estes-Gutperle solutions \cite{DHoker:2007hhe}.
