论文摘要
我们基于具有最小耦合标量场的多维$ f(r)$重力,开发一个没有小参数的通货膨胀模型。该模型由空间扩展的两个阶段描述。第一个始于围绕D维planck质量的能量尺度,并以我们空间的DE Sitter指标和最大对称的额外尺寸结束。在下文中,量子波动会在DE Sitter空间中迅速产生的因果关系中产生广泛的不均匀额外指标。我们找到一个特定的额外空间度量,该指标可导致适合观察数据的有效的Starobinsky模型。
We develop an inflationary model without small parameters on the basis of multidimensional $f(R)$ gravity with a minimally coupled scalar field. The model is described by two stages of space expansion. The first one begins at energy scales about the D-dimensional Planck mass and ends with the de Sitter metric of our space and the maximally symmetric extra dimensions. In the following, the quantum fluctuations produce a wide set of inhomogeneous extra metrics in causally disconnected regions quickly generated in the de Sitter space. We find a specific extra space metric that leads to the effective Starobinsky model that fits the observational data.
