我们研究 M 理论中的通货膨胀解决方案。包括四阶曲率校正项，我们找到了三个广义德西特解，其中我们的 3 空间呈指数扩展。采用其中一个解决方案，我们提出了早期宇宙的暴胀情景。这为我们提供了膜世界中大额外维度的自然解释，并提出了基于大额外维度的膨胀的 60 e 折叠膨胀与 TeV 引力之间的某种联系。
We study inflationary solutions in the M-theory. Including the fourth-order curvature correction terms, we find three generalized de Sitter solutions, in which our 3-space expands exponentially. Taking one of the solutions, we propose an inflationary scenario of the early universe. This provides us a natural explanation for large extra dimensions in a brane world, and suggests some connection between the 60 e-folding expansion of inflation and TeV gravity based on the large extra dimensions.
