摘要

This chapter reveals how quantum fluctuations of gravity evolve around the inflationary solution obtained in Chap.  7 . The goal is to investigate the evolution of the fluctuations from long before the Planck time until just before the spacetime phase transition, and to derive the primordial spectrumPrimordial spectrum which gives the initial condition of the current universe.
