规范超引力的广义Scherk-Schwarz约化

Generalised Scherk-Schwarz reductions from gauged supergravity

Gianluca Inverso

摘要:

描述了一种构造规范超引力广义Scherk-Schwarz隆起的方法。内部流形,通量和一致截断Ancillary都来自嵌入张量的低维理论。我们首先描述的程序来构建广义莱布尼茨parallelizable空间的框架的矢量分量嵌入在伴随表示的规范群,指定的嵌入张量。这使我们能够恢复文献中已知的广义Scherk-Schwarz约化,并证明$ω$变形SO(p,q)规范最大超引力的隆起的不可行结果。然后,我们扩展到任意广义莱布尼茨parallelisable空间,这原来是环面纤维化流形上的类。

英文摘要:

A procedure is described to construct generalised Scherk-Schwarz uplifts of gauged supergravities. The internal manifold, fluxes, and consistent truncation Ansatz are all derived from the embedding tensor of the lower-dimensional theory. We first describe the procedure to construct generalised Leibniz parallelisable spaces where the vector components of the frame are embedded in the adjoint representation of the gauge group, as specified by the embedding tensor. This allows us to recover the generalised Scherk-Schwarz reductions known in the literature and to prove a no-go result for the uplift of $ω$-deformed SO(p,q) gauged maximal supergravities. We then extend the construction to arbitrary generalised Leibniz parallelisable spaces, which turn out to be torus fibrations over manifolds in the class above.
