本文研究了在暴胀前物质主导时代形成的小黑洞对de Sitter空间中标量场标度不变功率谱的修正。这种黑洞的形成概率估计从原始高斯密度波动。本文确定了Schwarzschild-de Sitter空间中无质量标量场的Keldysh传播子对标量宇宙学扰动谱的修正。我们的研究结果表明，这种效应足够强，可以通过观察来检验，甚至可能被排除。
We study the correction to the scale invariant power spectrum of a scalar field on de Sitter space from small black holes that formed during a pre-inflationary matter dominated era. The formation probability of such black holes is estimated from primordial Gaussian density fluctuations. We determine the correction to the spectrum of scalar cosmological perturbations from the Keldysh propagator of a massless scalar field on Schwarzschild-de Sitter space. Our results suggest that the effect is strong enough to be tested — and possibly even ruled out — by observations.
