摘要:

我们表明,最小的必要成分,以构建明确的,四维德西特解决方案IIA弦论在树的水平是O 6-平面,非零罗马人的质量参数,形式通量,和负的内部曲率。为了说明我们的一般结果,我们构造这样的最小简单的deSitter解决方案,从一个orientifold紧紧的紧双曲空间。在这种情况下,只有两个模量,我们证明,它们是稳定的,足够弱的耦合和大的体积制度。我们还讨论了更一般的度量通量建设的情况下推广。

英文摘要:

We show that the minimal set of necessary ingredients to construct explicit, four-dimensional de Sitter solutions from IIA string theory at tree-level are O6-planes, non-zero Romans mass parameter, form fluxes, and negative internal curvature. To illustrate our general results, we construct such minimal simple de Sitter solutions from an orientifold compactification of compact hyperbolic spaces. In this case there are only two moduli and we demonstrate that they are stabilized to a sufficiently weakly coupled and large volume regime. We also discuss generalizations of the scenario to more general metric flux constructions.
