  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.
