我们继续研究暴胀全息时空模型中的暴胀波动。我们认为，通货膨胀的全息理论为通常所说的 dS/CFT 提供了物理背景。全息理论是一种量子理论，在大量电子折叠的限制下，产生了 $S^3$ 上的场论，它是 SO(1,4) 酉表示的表示空间。这不是传统的 CFT，我们不知道相关函数的详细非微扰公理。然而，两点和三点函数完全由对称性决定，并且有几个常数（实际上是背景 FRW 几何结构的函数）与单场慢滚膨胀模型中计算的常数一致。与慢滚唯一显着的偏差在于张量波动。我们预测所有三个保角不变张量 3 点函数的张量倾斜为零且权重大致相等（除非奇偶性强加为对称性）。我们讨论了我们的结果与 Maldacena、McFadden、Skenderis 等人的结果之间的关系。当前数据可以用对称性和一些一般原理来解释，并且与包括 HST 在内的一大类模型一致。
We continue the study of inflationary fluctuations in Holographic Space Time models of inflation. We argue that the holographic theory of inflation provides a physical context for what is often called dS/CFT. The holographic theory is a quantum theory which, in the limit of a large number of e-foldings, gives rise to a field theory on $S^3$, which is the representation space for a unitary representation of SO(1,4). This is not a conventional CFT, and we do not know the detailed non-perturbative axioms for correlation functions. However, the two- and three-point functions are completely determined by symmetry, and coincide up to a few constants (really functions of the background FRW geometry) with those calculated in a single field slow-roll inflation model. The only significant deviation from slow roll is in the tensor fluctuations. We predict zero tensor tilt and roughly equal weight for all three conformally invariant tensor 3-point functions (unless parity is imposed as a symmetry). We discuss the relation between our results and those of Maldacena, McFadden, Skenderis, and others. Current data can be explained in terms of symmetries and a few general principles, and is consistent with a large class of models, including HST.
