论文摘要
弦理论是一切理论的主要候选人。但是，必须在十个维度上定义它才能保持一致。为了获得4D物理学，应将其他6个维度卷曲在小紧凑的歧管中，此过程称为弦乐紧凑型。在这篇综述中，我们将回顾不同的紧凑型方案，证明在没有磁通的情况下，紧凑型歧管必须是卡拉比yau歧管。然后，我们使用广义复合几何形状审查与通量的压缩。然后，我们讨论宇宙学中的某些应用，例如Swampland项目以及从中得出的宇宙学模型。然后，我们讨论非相对论的弦理论，并为此类理论引入环形紧凑。最后，我们讨论了该领域的一些开放问题。
String theory is the prime candidate for the theory of everything. However, it must be defined in ten dimensions to be consistent. To get 4D physics, the 6 other dimensions should be curled up in a small compact manifold, this procedure is called string compactification. In this review, we will review different compactification schemes proving that in absence of flux, the compact manifold must be a Calabi-Yau manifold. Then, we review compactifications with flux using generalized complex geometry. We then discuss some applications in cosmology like the swampland project and the cosmological models derived from it. We then discuss non relativistic string theories and introduce a toroidal compactifications for such theories. Finally, we discuss some open questions in the field.
