Holographic bounce
  We investigate the bounce realization arising from the application of the
holographic principle in the early universe, inspired by its well-studied
late-time application. We first consider as Infrared cutoffs the particle and
future event horizons, and we show that the decrease of the horizons at early
times naturally increases holographic energy density at bouncing scales, while
we additionally obtain the necessary null energy condition violation.
Furthermore, adding a simple correction to the horizons due to the Ultraviolet
cutoff we analytically obtain improved nonsingular bouncing solutions, in which
the value of the minimum scale factor is controlled by the UV correction.
Finally, we construct generalized scenarios, arisen from the use of extended
Infrared cutoffs, and as specific examples we consider cutoffs that can
reproduce $F(R)$ gravity, and the bounce realization within it.
