In this paper we extend previous work on the relation between the complex structure moduli of the underlying Calabi-Yau manifold in five dimensional supergravity with the time evolution of an embedded 3-brane. We numerically solve the fields' equations for such a construction and focus on dust and radiation filled branes; with the possible application of modeling the universe as a brane-world. It is shown that in both cases the time evolution of the moduli causally connects to the expansion of the brane-world. We also find that in most cases considered there is an early short period of rapid accelerative expansion, indicating an inflationary epoch. We report on these results; leaving analysis of the underlying causes for future work.

膜世界和卡拉比-丘复合结构模量

在本文中,我们扩展了先前关于五维超重力中底层 Calabi-Yau 流形的复杂结构模量与嵌入的 3 膜的时间演化之间关系的工作。我们对这种结构的场方程进行数值求解,并专注于充满灰尘和辐射的膜;将宇宙建模为膜世界的可能应用。结果表明,在这两种情况下,模量的时间演化都与膜世界的扩张存在因果关系。我们还发现,在考虑的大多数情况下,存在早期的快速加速扩张时期,表明进入了通货膨胀时期。我们报告这些结果;留下分析未来工作的根本原因。
