The Evolution of Adiabatic Density Perturbations
Abstract
The evolution of adiabatic perturbations has been studied in Friedmann-Lemaître universes containing a mixture of non-interacting matter and radiation. The differential equation governing the growth of infinitely long adiabatic fluctuations has been derived. In the case of the Einstein-de Sitter universe, an exact solution is given to this differential equation.
