我们利用AdS/CFT对应继续研究文献[1]中介绍的强耦合暴胀子的性质。这些性质与传统的暴胀模型有质的不同。例如，在慢卷暴胀中，暴胀子的速度不是由势的形状决定的;微调问题涉及对偶红外几何而不是势;非高斯性，如局部形式，可以自然地变大。
We continue to investigate properties of the strongly coupled inflaton in a setup introduced in ref. [1] through the AdS/CFT correspondence. These properties are qualitatively different from those in conventional inflationary models. For example, in slow-roll inflation, the inflaton velocity is not determined by the shape of potential; the fine-tuning problem concerns the dual infrared geometry instead of the potential; the non-Gaussianities such as the local form can naturally become large.
