Cosmological Models (Cargèse lectures 1998)
Abstract
The aim of this set of lectures is a systematic presentation of a 1+3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models. In giving (i) the basic 1+3 covariant relations for a cosmological fluid, the present lectures cover some of the same ground as a previous set of Cargèse lectures \cite{ell73}, but they then go on to give (ii) the full set of corresponding tetrad equations, (iii) a classification of cosmological models with exact symmetries, (iv) a brief discussion of some of the most useful exact models and their observational properties, and (v) an introduction to the gaugeinvariant and 1+3 covariant perturbation theory of almostFriedmannLemaîtreRobertsonWalker universes, with a fluid description for the matter and a kinetic theory description of the radiation.
