Abstract
We introduce the cosmic holographic bounds with two uv and ir cutoff scales, to deal with both the inflationary universe in the past and dark energy in the future. To describe quantum fluctuations of inflation on sub-horizon scales, we use the Bekenstein–Hawking energy bound. The Hubble bounds are introduced for classical fluctuations of inflation on super-horizon scales. It turns out that the Hubble entropy bound is satisfied with the entanglement entropy and the Hubble temperature bound leads to a condition for the slow-roll inflation. In order to describe the dark energy, we introduce the holographic energy density which is the one saturating the Bekenstein–Hawking energy bound for a weakly gravitating system. Here the uv (ir) cutoff is given by the Planck scale (future event horizon), respectively. As a result, we find the close connection between inflation and dark energy.
