论文摘要
我们研究了宇宙膨胀期间大型波长时空波的发射，这是由反反应效应产生的。例如，我们研究了具有可变时间尺度的通货膨胀模型，其中宇宙的尺度因子随着时间的力量而增长。粗粒磁场来描述时空波，是通过使用征税分布在波数空间上定义的。计算了这些波在宇宙学量表上的规范的演变，并表明随时间减少。
We study the emission of large-scales wavelength space-time waves during the inflationary expansion of the universe, produced by back-reaction effects. As an example, we study an inflationary model with variable time scale, where the scale factor of the universe grows as a power of time. The coarse-grained field to describe space-time waves is defined by using the Levy distribution, on the wavenumber space. The evolution for the norm of these waves on cosmological scales is calculated, and it is shown that decreases with time.
