论文摘要
我们研究弦宇宙学中的失控，主导的时期。我们展示了体积模量的明显经典分解失控，该模量在4维EFT中描述了，可以将其升至10D的经典Kasner解决方案，在10D中，非紧凑型尺寸向大键崩溃。这也可以推广到任意时空和压实维度。我们以一些评论的评论，以了解如何通过量子效应修改这张图片，以及对动力学和运动学划线约束的需求。
We study runaway, kination-dominated epochs in string cosmology. We show how the apparent classical decompactification runaway of the volume modulus, described by a kination epoch in the 4-dimensional EFT, can be uplifted to a classical Kasner solution in 10d in which the non-compact dimensions collapse towards a Big Crunch. This can also be generalised for arbitrary spacetime and compactification dimensions. We conclude with some comments on how this picture is modified by quantum effects, and the need for both dynamical and kinematical Swampland constraints.
