论文摘要
我们对非苏匹马对称性进行了分类，并在$ d = 4 $之内进行扰动稳定，最大$ d = 4 $ supergravity的ads真空，并在超级巨大的大型领域中进行二合一ISO（7）测量。在该领域中建立了七个这样的真空，所有这些真空都会引起非supermmetric $ \ textrm {ads} _ {4} \ times \ times \ textrm {s}^{6} $ type IIA背景，带有和不带非无迹线和内部磁性。然后，我们在这些背景下分析了各种探针D $ p $ branes的动态，以搜索潜在的Brane-jet不稳定性。在所有这些情况下，这种不稳定性都是不存在的。最后，研究了通过隧穿的替代衰减渠道，重点是七个背景之一。我们也没有发现不稳定性，但是分析仍然没有定论。
We classify the non-supersymmetric, and perturbatively stable within $D=4$, AdS vacua of maximal $D=4$ supergravity with a dyonic ISO(7) gauging in a large sector of the supergravity. Seven such vacua are established within this sector, all of them giving rise to non-supersymmetric $\textrm{AdS}_{4} \times \textrm{S}^{6}$ type IIA backgrounds with and without non-trivial warpings and with internal fluxes. Then, we analyse the dynamics of various probe D$p$-branes in these backgrounds searching for potential brane-jet instabilities. In all these cases, such instabilities are absent. Finally, an alternative decay channel through tunnelling is investigated, focusing on one of the seven backgrounds. We do not find instabilities either, but the analysis remains inconclusive.
