Primordial Density Perturbation - Lyth, David H. (Lancaster University) a Liddle, Andrew R. (University of Sussex)

The origin and evolution of the primordial perturbation is key to understanding structure formation in the earliest stages of the Universe. Giving a thorough account of theoretical cosmology and perturbations in the early Universe, this graduate-level textbook describes their observational consequences and how such observations relate to primordial physical processes.
