Abstract

We investigate infrared logarithms in de Sitter space from holographic perspective. We employ a gravitational Fokker-Planck equation to investigate the time evolution of the de Sitter entropy S=π/(GNH2)S=\pi/(G_N H^2), where HH is the Hubble parameter and GNG_N is the Newton's constant. Under the Gaussian approximation, we obtain the dynamical β\beta function of g=1/Sg=1/S. It is asymptotically free toward the future. It also possesses the ultraviolet fixed point indicating that the Universe started the de Sitter expansion at the Planck scale. The pre-inflation era exists to prepare a special initial condition for the inflation era as a quantum remnant.
