Contribution

It analyzes the applicability of holographic entropy bounds to inflationary quantum fluctuations and clarifies their implications for early universe cosmology.

Findings

No constraints on inflation from holography.

Distinction between large and small scale entropy.

Suggestions for future research directions.

Abstract

In this paper the relevance of holographic entropy bounds in the context of inflation is investigated. We distinguish between entropy on large and small scales and confront the entropy of quantum fluctuations in an inflating cosmology with the appropriate entropy bounds. In conclusion we do not find any constraints on inflation from holography, but some suggestions for future studies are given.
