标题： Cosmological significance of one-loop effective gravity

摘要： 我们研究了宇宙学背景下引力的一圈有效作用量，以确定量子修正对爱因斯坦理论可能产生的宇宙学效应。 通过考虑玩具模型中普遍非定域项的影响，我们表明它们在极早期宇宙中可以起到重要作用。 我们发现，在暴胀期间，这些非定域项是显著的，导致与标准暴胀膨胀相偏离的结果。 显示英文摘要

摘要： We study the one-loop effective action for gravity in a cosmological setup to determine possible cosmological effects of quantum corrections to Einstein theory. By considering the effect of the universal non-local terms in a toy model, we show that they can play an important role in the very early universe. We find that during inflation, the non-local terms are significant, leading to deviations from the standard inflationary expansion.
