Fluctuations in Inflation

Part of the Springer Theses book series (Springer Theses)


Inflation expresses an exponential growth of the scale factor of the Universe in the early time, namely, \(a \sim e^{Ht}\). In Einstein gravity, this requires \(p \sim -\rho \) with \(p\) and \(\rho \) being the pressure and energy density, and is often realized by the existence of a scalar field, inflaton.
